I have had some experience "fooling around" with a home made guitar. My attempts were with alum. "L" bar riveted together and using bicycle s/s spoke nipples and pieces of s/s spokes as the tensioning device. Problem with alum. is is that it is soft. After a few months the frame warped-- all those strings under tension probably did it. But then, if alum is soft, the rivets are even softer, and when I tightened up a few wires one fateful day, I ended up shearing off the heads of the rivets.

Thing is, in order to cut a slab of ganache, the wires have to exit the slab to make a clean cut. This means the wires have to end up below the slab when the cut is finished. To do this, I took a large nylon cutting board, and cut a series of 1/8" deep x 1/8" wide grooves in it with a table saw. This does the trick, but now I had to anchor and hinge the frame to the base, as any shifting when I pushed the frame down would make for messy cuts. And, a lot of crud gathered in the grooves of the cutting board. Probably close to 100 hours of farting around and "Wile E. Coyote Back to the drawing board" moments fooling around with this contraption, and now it sits in the attic of my garage.

I do 3 slabbed ganache varieties at work. What I use is a cutting wheel. At dollar stores, I buy a dozen s/s pizza wheels, usually 3" dia. I cut out the rivets, throw away the handles, and mount the wheels on a length of redi rod (all-thread rod) I have a lathe at home so I turn sections of hollow oak, cut them to 7/8"lengths, and space the wheels with these, make some handles, and cap off both ends with acorn nuts. Matfer has a version of this, which I un-shamefully ripped off, the 2005 catalouge listed it for over 300 USD. A picture is worth a thousand words...

After I pour out the slab, I wait until semi-firm, not fully crystalized, and then paint on a top layer of couverture, flip it over, then paint on a bottom layer. I put my contraption in the oven for a minute or so and then cut through the slab in strips, then in squares. Works quite well , and I spent far less than 10 hours making the thing.........

Hi Andy,

welding aluminum is matter of professionals, i built this frame when i just arrived in SA and i didn't know anyone. So i went the easier way to "rivet" (or bracketing) everything simply because was the only way i knew how to put it together.

Riveting is easy: drill a hole, put a rivet and with the right gun just close the rivet.

The bolts are the same as the one from the link, any engineering company is capable to drill a hole in it. Do not try at home, it will cost you so much on drill bits and time. Seriously i did all the rest of the job with the cheapest DIY tools i could find at a builder warehouse.

the frame has been put together almost 2 year ago and it hasn't yet broken into pieces... so i guess it works!

Next (just to consider it an evolution) i will buy a thick cutting block and cut the slots so it is easier /faster to cut and move the ganache.

looking forward to see yours!

Cool Antonino. It looks like you went for bracketing instead of welding it. A few other deviations from the plans you posted. Any further modified notes on how you made yours? It looks a bit easier to construct.

Here a picture of mine!

DIY is very very cheap,i would say 2 hours for shopping and 2 hours to put it together (the first one i made took me a lot longer... trial and error) if you get someone to do it (unless is a friend) it will look better but cost also more.

i use an elevated cutting board so i can push it trough the ganache.

sometimes i use it just to score the marks on a soft caramel and then cut with the knife...

still, only ca $40...... i can live with that!

Clay,

Agreed. Looking to see if we can do the whole thing in a manner that keeps the weight down so that it can bemoved easily and is durable enough to withstand the moving and workload.

I have a SS fabricator friend in FL I was thinking of approaching with the concept as well. It'd be neat to see someone in America producing these that doesn't cost so much. It's not rocket science.

For now though I just want a hacked solution to get the job done.

Posted in: Geek Gear - Cool Tools (Read-Only)

Yea I looked at that again recently as a thought. I don't really want a push through though. Either a top down push (whether on a rail or free-form) or hinged idea.

Push throughs could work good for straight ganache but if you do any nuts* or soft-caramels (*caveats abound but they can be done with standard guitars) it would cause too much tearing with this system.

Pete:

The footprint may be a bit large, but one advantage of doing something like this is that it's totally portable. When you're not using it ... just pick it up and slide it out of the way. It's not permanently taking up work/counter space.

Andy,

I have a welding buddy who says he can put one together with alum. but I have to say, the one Clay shows is very interesting. The only downside I see is the required footprint. It's a manual version of what SG is selling for 6500.00. The wheels are turning......

Andy:

Here is one I saw in Bolivia when I was there in November 2010. It uses guitar tuning pegs (and guitar strings)! Tiny holes are drilled through the base, as you can see in the photo, and the guitar strings are threaded through. Of course, you'll need to replace the wood with a material that's food safe, but it works well. It's pretty cool, actually. Push through in one direction, rotate the entire device 90 degrees and push through in the other direction.

What I like about this compared with other approaches is that it doesn't require the precision of machining the slots in the base to accommodate the strings, and there is no hinge. It does require more elbow grease than a hinged guitar, but it's a comparatively simple device to build.

Excellent! I am great with chewing gum, paperclips, and wire cutters.

If you can find your details that'd be great, much appreciated.

DIY Guitar

Posted in: Geek Gear - Cool Tools (Read-Only)

Hi Andy,

i actually did! i found some details online (will try to remember and forward the links).

you will need:

a) being good as "MacGyver'

b) few tools

what i did: i bought some aluminum pipes of 25mmx25mm and cut to size to create a frame.

riveted all together. made holes for the right cut size ( 2.5cm )

Then i bought some high resistant bolts and got the holed by an engineer company ( in Cape Town we have a lot of them that work with marine items).

The wires are not from an electric guitar (too expensive) but is fishing rod for deep see fishing (sharks, tuna etc) that can hold pressure up to 300kg.

the next step would be to get a base cut from a piece of aluminum (like a real one) but i don't feel now to pay $$$ for it.

Now, it looks very "frankestein" BUT it works!

I will try to take some pics tomorrow.

BTW, a frame cost me about Zar 350 (ca $45)

Anyone built their own Guitar? I really don't want to expend resources on one right now and my brain just can't come up with the justification for the cost association, always seems like highway robbery. We're starting to move out of hand rolled though and cutting with a knife is tedious.

In my head I've got PVC pipes in a square with stainless strings tightened by eyelets or thumbscrews spaced however seen fit with a hinge.

So--built your own? Come across some plans for a DIY project? If I could spend a few hours and < a couple hundred I'd feel it was a worthy small project.

Color fade

You know come to think of it I've never seen our transfer sheets fade. There must be something out there that has a more reliable or longer color hold that isn't toxic.

"In these black bags we have 2 colored pretzel sticks.", heheh!

We've noticed colors can fade in the dark as well, might be an oxidization thought to it. Mainly it is our blues that go--sometimes red but it's not consistent. Same things happen with some of our icing colors with cakes.

Love to know a trick or brand that has more resilience. We want to try the food-based-colors as well. Neat to see if beets do the same.

What is the best coloring method to prevent or decrease color fade?

Im currently using oil-based colorings (Chefmaster and some Wilton) with white Callebaut couverture.

Until now, Ive only used small amounts of color for drizzle decorations on truffles. I have noticed a slight amount of color fade (especially with pink), but its not particularly noticeable, since there is so little of it.

Ive started doing solid chocolate lollipops with larger swaths of color. In particular, were doing some baby-themed pops (pink, blue, green, etc. filled in the deepest part of the mold, then completing the pop with dark, milk or white) that I want to sell through local hospital gift shops. Our test pops, however, are showing a significant amount of fade, just after a few days. They are currently packaged in cello bags.

Ive researched some other options like using a powdered colorant or colored cocoa butter. Could the cello bags be accelerating the fade? Any thoughts would be greatly appreciated.

Chocolate couverture training

Posted in: Opinion

Good day friends!

I am looking for a personalized hands on chocolate couverture training in Europe withan experienced master chocolatier. I would like to extend my knowledge in making [Ed: working with] chocolate couverture (not bean to bar). I am mainly interested in learning the science behind it all, and how each and every ingredient interacts with the others. Why use this and not that? How the addition of a certain percentage of a certain ingredient affects the chocolate (i.e., flavour, texture, aroma, shelf life...)

Any recommendations other than the renowned Callebaut academy?

Thank you,
Omar

Pricing

Posted in: Opinion

Just curious....

Have you asked them what THEIR budget is?

THEIR budget, not yoursis your starting point.

Quite often organizations will dangle the carrot of "exposure to new customers" as an incentive to bring your price down and/or almost work for free. I promise you that you will get very little business from an event like this. You need to find out what they can spend on dessert, and then see what you can do to make something for them AT A PROFIT. It's a business summit. They'll understand if you tell them you can't work profitably within their budget.

It's also ok to walk away from business opportunities if they simply don't make sense financially. Remember.... Your business isn't a charity. You have bills to pay just like every other business, and in fact handing opportunities like this to your competitors is a good thing in some ways. Let THEM work for free!

Cheers

Pricing

Posted in: Opinion

There's another way to do this, which is to research what other (caterers) are charging for similar items. I do this a lot on my projects.

If a survey of caterers and venues reveals that they charge $7/pp for a dessert then you know what the market will bear - you know the maximum you can charge. Taking a much closer look at food costs (Antonino is right - $2-$3 is too wide a range), you can mark your costs up to reflect the other costs (labor, overhead, delivery) to arrive at a final price. I would recommend you consider thinking about gross margin, not markup.

What's the difference? For an item with $3 in total costs, a 50% markup results in a final price of $4.50. On the other hand, a 50% gross margin results in a final price of $6.00. An item with $2.25 in ingredient and labor costs and a gross margin of 45% results in a final price of $4.10 - you'd factor in all your other costs into the final price -- $4.10-$2.25 = $1.85 gross profit/unit before other costs.

The general formula for calculating a final price based on a gross margin percentage is:

Final price = cost price / (1 - margin percentage)

$4.10 = $2.25/(1-.45)

Pricing

Posted in: Opinion

Like Antonio and Andy have mentioned, it is very important to understand your costs. I actually have a catering company and before I prepare a quote, I always ask myself " How much money do I want to make on this project?." Then I go about analyzing my costs to come up with a price for the client. Good luck. This is a tricky thing to figure out, but you will.

Pricing

Posted in: Opinion

Pricing is always derived from your COGS or COGS+L(abor) numbers. It's hard to arbitrarily price something as you're requirements and overhead are different from my own. You also want to be above your margin threshold, for some it's 300% for some foodservice they are lucky to get 80% so YMMV.

Just noticed Antonino's post and he's right on.

Pricing

Posted in: Opinion

H,

pricing is a big science, so many things to calculate: food cost, overheads, profit but also market related prices, high potential profit for once-off or lower price to create a long lasting client/business relationship!

So start to have your food cost (ingredients per portion) right: $2-3 is a very wide range!

THEN do this calculation: food cost (FD) X 65% = minimum selling price. (eg: $2X1.65=$3.30-min.selling price)

or: final price is equivalent to: FD +15% (oveheads)+55% (minimum profit) (considering your food cost being 35%)

Also remember to add to your costing any extra tool/trais, foil, petrol etc necessary to get the job done. ( let say 5-10% )

As well: do you need to hire extra people for the job? Add it on. Do you need to work extra hours for the job? if you will do it on your extra time, add it on: you could have been doing something else but you stuck at work till late night!

Then you will see, if this price isbelow your competitors or market related you can add as much as you feel :a) right; b) fair c) worth the effort d) try to cash up heavily to buy a new tool/ great dinner/a day at the SPA....

my suggestion? it should be worth the effort and the extra time without being to heavy on mark up..

Remember that unless you are happy at the end of hard work, you will feel very very bitter about it and you will not appreciate what you did.

My few rand (south african money..) worth of knowledge...

Hope it helps

Ive been offered my first catering job: to create 150 desserts while keeping with the theme of my very new chocolate business. The dessert is to follow a dinner following a summit on local businesses and mine has been chosen to make dessert. I have decided on giving them a choice of one or the other or both and letting the people choose like a menu. First is a dark chocolate mousse served in a white/milk chocolate cup garnished with chocolate covered orange peel the second is a square of white chocolate raspberry cheesecake(no crust) enrobed in dark chocolate. I have never priced something like this out before but have calculated that I could make each dessert for around 2-3$ I would like to make a reasonable profit on this job but also don't want to over charge. I was thinking 500-550$ for one dessert for everyone or 650-700 for the option of one or the other. Is anyone out there familiar with these kinds of things?

Makeshift Tempering Machine

Posted in: Tech Help, Tips, Tricks, Techniques

There is a cheaper and easier route...

Go to a drugstore and get the cheapest heating pad (electric blanket). The more expensive ones have auto-shut off and terry clothe covers which you don't need.

I just flip over a 1/2 sheet pan on the counter, put the heating pad on top, the bowl or hotel pan of cold couverture on top, and walk away overnight. The "medium" setting is usually pretty darn close.

Stirring is a different matter. Chocolate is thixotropic, which means it is best mixed with a shearing action, any other action for longer periods of time usually incorporates bubbles. Most melters and temperers usually use a wheel/disc with a scraper, or a rotating bowl with a scraper.

Makeshift Tempering Machine

Posted in: Tech Help, Tips, Tricks, Techniques

Another problem: What temperature does the hotplate get to? Chances are it gets much hotter than the contents are intended to get, and as a result could burn your chocolate - especially if it's not being moved off of the bottom. Case in point: Even a baine marie will burn your chocolate if you let the water boil and not remove the chocolate from the sides and bottom of the bowl.

My recommendation: If you're going to waste time "rigging up devices" to try and do what's already been invented and proven to work, put in a few more hours at your paying job, save your $$ and buy the right tool for the job - a proper tempering machine. They aren't that expensive.

I also think this stirrer would not work as well as you would need it to and I don't think the other stirrer you linked in your reply would do the job either. In my opinion, you'd be better off saving that money for the future and buying a tempering machine rather then spending money of somethingthat probably won't work and/or would be a big hassle.Also, it doesn't seem like you'd be able to temper that much chocolate at once using this equipment. For the amount you could temper using this magnetic stirrer, you'd be just as well off tempering by hand. You can temper a couple pounds of chocolate in maybe 15-20 minutes. To answer your question about tempering, no - tempering is not just about achieving the correct temperature for crystal formation. It most definitely has to do with agitation as well. I highly recommend you know how to temper correctly by hand prior to becoming reliant on equipment. It is a really helpful skill to have. Also, there is a lot of info in JP Wybauw's books about crystal formation, tempering, etc that is good reading. Good luck.

Hi Nat,

Thanks for your reply. I have a few follow-up ideas I'd like to see if you have any thoughts on.

1) The company that makes this hotplate also sells magnetic stirrers up to 5 cm long. That still won't scrape the sides but at least it's bigger than the standard magnetic stirrer that comes with it.

2) I could conceivably rig up some sort of scraping device which would fit the pan and have the stirrer embedded in it. I'm not sure if the magnetic stirrer would be powerful enough to move such a large attachment though.

3) Maybe something like this http://www.ardentegourmetstirrer.com/ would do the trick?

4) This one is a bit more technical but you seem like the kind of person who would know the answer. Here's my understanding of the tempering process:

Type V cocoa butter crystals will form in the 29-34 C range.If you just let chocolate sit at this temperature all of the crystals will eventually be type V but the time required for this to happen is prohibitive for any commercial confectioner.Agitation will reduce this time, as will various temperature fluctuation or seeding techniques.

So if I'm willing to let the chocolate sit on the hotplate overnight will it still be tempered? Or does agitation play some other role in the tempering process? If I just used a small stirrer and it agitated the chocolate for a long time would the gradual movement and convection near the sides of the container be sufficient to temper the entire mass if I let it sit for long enough?

Any thoughts would be appreciated.

Makeshift Tempering Machine

Posted in: Tech Help, Tips, Tricks, Techniques

a magnetic stirrer as I know from labs I've worked in will not stir thechocolate very well. You need to make sureyou get all thechocolate off the walls on each stir as most tempering machines do, whereas a magnetic stirrer is a short ~1" bar that will only stir a small area in the bottom center of viscouschocolate.

-Nat

I was thinking of getting one of these:

as a makeshift tempering machine.

I plan to put a water bath on the hotplate and put a pot in the water bath.

I would be using it at home to make small batches of chocolate for holidays and such.

Can anyone think of a reason that this wouldn't work? It's a good deal cheaper than a tempering machine and more versatile too. I could just dial in a new temperature and use it for sous-vide or custard or some recipe that would make use of the magnetic stirrer.

Price is $USD12/kg FOB - you pay the postage and insurance on top of this price (allow $USD7-17/kg airfreight around the world - by ship can take 4 weeks plus, but is cheaper). We are currently sending 400kg to 5 new roasters, we now have 2 batches of 70% dark chocolate made in Adelaide and Melbourne (Australia) - this is just our first sample packaging

We also have 2-3 tonne available now should anyone be interested............our cocoa growers can prepare more if it is needed.....we have so many mature pods needing a good home. If interested, contact Tupa'e Steve on stevebrownsamoa@gmail.com and we can try and assist you. We can even send our testimonials from our roasters' initial batches prepared. Samoan Trinitario has always had a fine reputation since the early German cocoa plantation days in the late 1800s. Samoans today still consume a lot (50 tonnes annually) of locally prepared cocoa (Koko Samoa) and it is excellent.
