I think next time I am in Australia I would love to pop over .. I'll call you before hand .. do you know any good place here in NZ that might be able to lend me a hand ??? I am eger to learn and vedios on the internet give a bot of help but does not really make you feel the exsperince and most are so diffrent than what I need to do .. I really really apprciate you taking the time to reply to me .. its indeed very kind of you.
A bit too far for a drive to Adelaide in South Australia to see how we are doing it.
i live in Hamilton, Waikato in New Zealand
I would suggest that you:
a. Do a lot more reading about chocolate tempering.
b. Find a method that would be suitable to your situation.
c. Practice with chocolate to learn how to achieve the correct temper (this you can do with normal chocolate from the supermarket). Remember that you canmelt and temper again and again so there is no waste. There are a few methods of tempering that work on the small scale beside seed tempering.
d.Once you have agood feel for this you can practice with your chocolate till you find the best way of doing it.
There are polish and varnish products that are used for panned goods (made with untempered chocolate) but this is a very complex application process.
If your chocolate will be well tempered it will be nice and shiny without any need for spraying.
Where abouts are you?
Thank you so much for that .. my next step now is that I need the choclate to be warm enough to cut !! that mean leaving it in a room of 16-18 dergee or sometime I put it in a cold low heat oven for few seconds just to give me enough time to make the product possible to cut in shapes with a cookie cutter tyep. is that again going to damage my Choclate!!
Also is there is any product out there that I can spray my choclate to make it more shiny ??
much apprciate your kind attention and time to reply. this is a very important subject for me and we dont have anyone near by that I can go for advice.
Thanks
I'm afraid that you may need to do a bit more reading on the subject of chocolate tempering.
Putting things in a really simplified way:
1. In hot (over 40-45C) chocolateall the cocoa butter present will bemelted, no crystals present.
2. Such chocolate needs to be cooled to around 25-28C so some of the cocoa butter present will crystalize. This crystalization will produce a variety of crystal forms (cocoa butter is polymorphic which means that it can crystalize in many different types of crystal forms).
3. Chocolate cooled in previous step with different forms of crystals is warmed up to 29-31C which melts the unstable crystals leaving only stable ones. This is tempered chocolate and can be used to form products that will not bloom and look good.
This is a very general process description and temperatures are just for indication.
In your case if you take the tempered chocolate and melt it at 40C you effectively melt all the cocoa butter crystals making chocolate untempered.
If you make product with such chocolate it will bloom.
If you have your bought chocolate already tempered you may try seed tempering where you add some solid tempered chocolate to liquid chocolate. Something along these lines:
thanks for your kind attention .. the chocolatethat I buy is pre-tempered so i just melt theboth type of chocolate in around 40Cin my Choclate machine :

You have not mentioned tempering your chocolate.
How do you temper?
Hi, I melt high quality belgium white chocolate then I mix peanut butter into it, I put it on a tray then I swirl pure 70% chocolate through it .. This has to set as after that i need to cut it in squares for serving!!
I do that at Home but I use a melting machine to melt my chocolate, then I put the tray in a chillier to cool down some time over night!! i take the tray out to warm the chocolate to a room tempture so I can cut the size i want.
some days the chocolate is looking super!! other time the chocolate get those little tiny white spots and blooming happen.
I am so disparate to know why some time its ok an other time its not .. some times even half the tray is good and the other is not. the ecstatic look of my chocolate as the taste is very important to me, so Please help with any advice out there.
also is there s anyting I can spray to make the chocolate look shiny without effecting the taste??
much apprciate any help.
For a patch of dark chocolate I'm working on and I want to add vanilla to it. What form of vanilla should I use while conching? ( whole vanilla pod/bean or vanilla powder) And at what stage is the proper stage should I add sugar, cocoa butter and vanilla into my chocolate?
Thank you

Hi Corinne, thank you for your suggestions, I will try them out.
I also want to put in a kudos for Renee at Chocolat Chocolat, she read my query here on TCL and contacted me with their 4 closest matches, and two of them might work for me.
I was very impressed, she went to a lot of work.
In gratitude,
Mack
Hi TCL friends,
I have Tomric bar molds, and get release marks. From research on this forum I get the impression this is due to the molds not being made by injection mold process. I emailed Tomric who said "Our molds are made out of sheets of polycarbonate, the sheets of polycarbonate are heated up and vacuum formed over the tooling". My guess is the injection molds are thicker and thus hold temperature more evenly?
So, I now am on a quest to buy injection PC molds. Chocolat-Chocolat does not have the size I want. I am looking for suggestions of which companies to contact. I looked at Pavoni, their website is not very user friendly, and I could not locate bar their molds. Micelli if I understand is set up to make custom molds. I just want to buy stock molds.
Specifically I am looking for bar molds, 4 cavities, each bar being approx 5.5" x 2.25" x .375, and the molds would have break apart lines. The Tomric molds I have feature all the above, but sadly leave the release marks.
Any advice would be greatly appreciated.
In thanking you in advance,
Mack
I am use Belcolade and Callebaut. I make mostly hollow, decorated articles. I like to work a little on the hot side in a cool room and let molds finish the tempering for me. The molded items are then packed in a plastic box ( that is not air tight) and there after placed in a cardboard box ( which is airtight). When I taste freshly molded items they taste fantastic with strong chocolate flavor and great melting. As the pieces get older 1/2/3/4 months the flavor becomes weaker and they no longer " instamelt".
When does it begin? immediately. it's a process who's rate depends on many things - total fat content, if you have milk fat present, and if so how much, are there nuts present, how 'good' was your temper to begin with, what are the storage conditions, etc.
Generally speaking, a good rule of thumb is that most of the changes are going to work their way out after a month. the chocolates certainly not done changing by that point, however the average person's not going to notice significant changes after that time.
Should you switch? that's a big question - that's entirely up to you. i don't know enough about what you're using, how you're using it, or what your customer want to answer that!
Undertempering a bit and sealing in air tight plastic wrappers could extend the peaks and valleys a bit, but undertempering's a very trickily proposition if you don't have a way of accurately measuring it, and many people don't have hot/cold sealers to seal their bars in airtight plastic overwrap film...
Sebastian,
When you say " over time". How long before the still liquid cocoa butter begins to solidify and at what rate?
I currently use fairly expensive chocolate that happens to agree well with my pallet and the pallets people that I have surveyed. Most of my products have at a minimum 3 months from being made to being eaten by the customer and in many cases customers hold on to our products for 6 months or longer (as they do not change much visually). When comparing my day old products to my month old products to my 3/6/9/12 month old products I have noticed " huge peaks and valleys" turning into foothills, which makes me ask two questions;
Since 6 months to a year later the difference in flavor is not as easily noticeable, should I keep using such expensive Belgian chocolate or switch to something domestic.
Is there a way that I could maintain the "peaks and valleys" for a longer period of time?
I appreciate your thoughts
Best
Victor
Chocolate flavor does indeed change over time in tempered chocolate - the main driver of this has to do with how tempering works. When you have a 'solid' tempered bar - there's still actually quite a bit of liquid cocoa butter present in it. Over time, much of that liquid cocoa butter will begin to crystallize and solidify (this is also why your chocolates get harder over time). The dynamics of flavor release with solid fat are quite different with the dynamics of flavor release with liquid fat. Generally what you'll see is a 'rounding out' of the flavors - where you might one have had huge peaks and valleys of flavor, you'll now have foothills. This isn't true for all flavor categories, and the ability of acids mitigation depends heavily on the type of acids you have present.
I will not comment on aging chocolate as a method of flavour development.
Yes you can take chocolate from the conche without tempering and mould it into big block using plastic trays(smaller 3-5kg blocks work better, easier to use later). After it sets take it out of the trays and keep for later use.
This chocolate will bloom very fast but this is not a problem.
You will need to melt it down again when you want to use it and in this proces you will melt all the unstable cocoa butter crystals that create bloom.
chocovision skimmer vs dispenser
skimmer is more expensive. But dispense just like the dispenser (cheaper). What are people paying more bucks for? I am debating on which one to get.
I will make molded chocolate bar.
Thanks
I'd like to hear about this too - specifically the bean-to-bar program
Make sure to attend the NW Chocolate Show this weekend - you should find what you are looking for there.
Hi y'all,
Freshly transplanted to Kirkland from North Carolina, I am looking to meet some local chocolate folk for talk, collaboration, or even for a job if there are any available. I have moved here so my wife can get her Doctorate. While I am here I would like to make the most of the amazing local chocolate scene and hope to work with dark chocolates, especially with added super foods such as blueberries, goji berries, blue green algae, etc. or perhaps even MMJ. If any of that sounds interesting to you, I would love to hear from you.
Thanks in advance!
Aloha,
I'm a beginner making chocolate in Hawaii with Hawaiian cacao. At first this was a challenge in my home 82 degree kitchen, but I am now getting a stable temper (does not melt in my hand), but a lot of my chocolates are getting white streaks and the outer layer of my last batch is completely white (see attached picture). With other batches, some have looked great. The only batch I have made that did not bloom at all had added cacao butter which I do not usually add and they are looking great a month later, so I am wondering if a factor is low fat content. In a previous batch of dark w/no butter, some had streaking and some did not. At the time I attributed that to the fact the streaked chocolates were the last to be molded and the melted chocolate was difficult to pour and had already cooled considerably and probably unevenly.
The batch pictured is 72% criollo with no added cacao butter. I've been letting my chocolate age in a bowl for about a week. By then it has tempered on it's own. It seems that doing this helps the stability of my end product but I don't know why. I realized I could probably do a seeding method with this, but I have been heating 4lb batches to 120 degrees, then cooling half on a slab of granite by hand with many fans, getting it down to 80-82 degrees, then back up to below 91. Then molding by pouring or syringes and using a heating pad for the melted chocolate. This white, problem batch I let harden at room temperature whereas I have hardened previous batches in the refrigerator. I decided to try room temp because the drastic temperature change and condensation upon removing my product seemed to affect its flavor over time.
Where am I going wrong? Any feedback on the art and science of tempering (Hawaiian) cacao much appreciated! Thank you!
I had this happen to me a few times in the past, but it was due to the humidity in the room. I haven't had it happen again since I got that under control.
I'm looking for help with an odd thing happening with Fumee De Sal smoked Sea Salt and our dark and milk chocolate. After we top the chocolate with the salt, hours later the salt begins to sweat; on some days, it went so far as to completely dissolve into salt water puddles on our chocolate bark. Temperature, humidity, and many other factors seemed to be the same or similar as many times when this did not happened. No other outside factors seem to play a part that we can deduce. Something was different! Any thoughts?
I don't understand what you mean about the percentage. Are you making a ganache? so with a compound you would use 3 parts chocolate to 1 part cream?
- If that is what you are asking, I'll defer to the more experience members of the chocolate life for that answer. We don't make any ganache center chocolates right now.
Searching this website will behelpful for that.
Thanks

Very simple to do: Get a 10cc syringe, weigh it and with the syringe on the scale set your scale to 0. Fill the syringe up to 10cc and weigh it. Divide by 10 and there's your density. In my experience it is around 1.27g/cc.
25% increments sound like too little control. I get very different roasts with each 10-20 degree difference, which is trivial to accomplish with the Gene Cafe. Are you supposed to cycle up and down between 50-75% to get a desired temp between those 2 points? How do you then map that to a convection oven?
Makes me want to shake the Behmor makers until they promise to learn about PID controls. No one really cares about *power in*, we only care about *temperature out*.
I was recently emailing with another small chocolate maker who told me about an upgrade to the Behmor that gives a lot more control (although not complete control). You can set the power to the heating elements from 0% to 100% in 25% increments as well as switch the drum speed between 8 and 16 rpm.
I believe that the new Behmor 1600 Plus is basically the old Behmor with this upgrade already installed. I think this would be good for doing tests on bean samples or small batches.
I've used a Behmor for a while - what's frustrating is the lack of control. I'd read about roast profiles in forums or books and be unable to apply it, so Iresold mine to a friend and got a Gene Cafe. It's a lower capacity but much higher control, ideal for nailing down roast profiles before going bigger.
Dedicated roasters resell well since there are a lot of coffee enthusiasts; you can try that option and resell if you don't like or outgrow it.
Hi there,
I am looking into some small scale home roasting roaster options. I've narrowed it down to about 3: Behemor 1600, CocoaT Junior Roaster from Cocoa Town, or a stainless steeldrum (RKdrums) hooked up to a rotisserie on my BBQ.
From what I've read, the Behemor is decent and not without its quirks, and only roasts about a lb max. $299 Reasonable price for the beginner.
The CocoaT Junior Roaster seems like a great option. 4-6 lbs at a time, beans rotate slowly in a stainless steel drum under convection heat. $450 Reasonably priced as well.
BBQ drum (depending on size) holds the largest capacity of beans for a home roaster. Depending on where you purchase, it can be quite expensive...upwards of $1000 for asmall size drum, including motor and rotisserie rod. You also need to modify your BBQ somewhat to ensure even heat distribution.
Has anyone used any of these 3methods? Is there another option im not exploring? Any insight would be valuable. Im especially interested if anyone has used the CocoaTown roaster. Thank you.
