I recently bought the book "Fine Experiences, Great Chocolate 3 - Extending Shelf Life" by Jean-Pierre Wybauw. This is what you need. It explains everything scientifically. I highly recommend it.

Yes. Cool the cream to about 90 degrees.

Wouldn't the 115 cream take the tempered chocolate out of temper?

How long would you say the shelf life would be by doing it this way?

I believe a butter ganache is also supposed to last longer than a cream ganache. Even more so if you use clarified butter.

In my experience, melting and tempering the chocolate being used in ganache is a ridiculously easy way to extend shelf life. Boil cream, cool to 115 degrees, THEN add to freshly tempered chocolate. Use an immersion blender to create an emulsion. It will be much more stable.

Thanks Ryan,

I am actually melting the chocolate first then adding the cream to this. But if it means a longer shelf life then I can change this to cooking the cream first.

I managed to find out that the problem with the lollies is due to sugar bloom. I was putting in the refridgerator then bringing out intoa humid room, therefor ecausing the bloom!

If you are cooking the cream and adding chocolate to it for your ganache it has a longer shelf life than you think. That is how I make mine and then roll into balls by hand before dipping them, get 3 months shelf life... even longer if stored in refrigeration. Your lollies crumbling sounds to me as though your chocolate is not tempered correctly and therefor has too much crystallization.

Hi,

I have just starting my own small business from home making Chocolate truffles. I make them with a ganache recipe of 400ml of chocolate with 150ml of double cream, I have been advising people that they have a shelf life of 5-7 days due to the cream content. I am now wanting to start selling them in local farm shops/delis but they all require a longer shelf life,

My questions on this are:

Does anyone have any advice on how I can make them have a longer life?

Does anyone know any truffle recipes that do not use cream therefore increasing the shelf life?

I also have also started to make chocolate lollies & chunks. I melt the chocolate and then leave to first set at room temperature then put in the fridge but my problem is when I take them out of the fridge and leave for a period of time at room temperature, they seem to look like they have separated and when you bite into them they go all crumbly. What am I doing wrong?

Please can someone help as I seem to have built up quite a few regular customers & I dont want to disappoint them.

Thanks from a new chocolate fan xx

Yup--go to Walmart and buy a $40 Hamilton Beach. Drew Shotts put me on to these. They do a great job and outlast R-C's and Cuisinarts. They have a plastic shaft and all the bad China stuff, but they last and last. The last time I made Praline, I caramelized the hazelnuts and tossed them in. Ran it for about 15 minutes until the oil released. It won't take it down to a totally smooth paste, but much better than the other options.

Forget about a Robot Coupe. It has a duty cycle of only 5 minutes. A cheap Hamilton Beach will work until the oil separates from the nuts.

Thanks Patti. I did this and it still was a nightmare to husk them all (but better than other ways). I'm going to buy paste next time. I used 7 cups of hazelnuts. It tastes wonderful, but what a pain.

When I mix a gianduja at home from commercially available products, I use ~50% milk chocolate and ~50% hazelnut praline paste (which is itself, ~50% sugar and ~50% hazelnuts). So breaking it down, mine is approximately 50% milk chocolate, 25% sugar and 25% hazelnut.

I'm not sure how much further/higher you can push that hazelnut %. Too far and the hazelnut fat will start to interact with the cocoa butter and make tempering the gianduja hard.I'd think you could go higher, but don't really know.

I forgot to ask, what's a reasonable range of chocolate to nuts? Can I do it without any milk powder or should I do at least a bit?

To remove the hazelnut skins more easily:

Gianduja is one of my favorite topics It comes out great from the grinder after a few hours. We did pre-grind in the food processor to make it easier.

The real pain is to quickly de-hull the hazelnuts. The rubbing on a wet cloth method works fine, but there are a few nuts which don't release their hull, it gets really hot and is time consuming.

Any alternatives for a better process? Any equivalent to the small scale winnowers we use for cacao?

The second major issue is sourcing quality hazelnuts consistently and making sure they are not rancid when you buy them. Treat yourself to the 35 part Gianduja series from Dallas Food Org.

Either a large colander or a wet cloth... Rub the hazelnuts against the screen of the colander or put them in the wet cloth, fold over itself and rub.

What's the best way to de-hull?

Thanks cheebs - that's what I was curious about. When I've "made" a gianduja for chocolate work, I've done so by mixing hazelnut praline paste and chocolate. I was wondering if the grinders could take the nuts/caramelised sugar without any problems, but it sounds like they can if I pre-grind.

Cheers

It does and that will work perfectly. It only takes a few hours to get the paste super-fine. Remember to de-hull the nuts!

Gap... I only roast the hazelnuts... if caramelized I would then be making pralin (which I actually do make by caramelizing, running through the Champion with the blocking plate in and finishing for a half hour or so in the Santha)

I'm assuming that if I put the hazelnuts through a food processor first the Santha should be able to take it from there. I wouldn't think I'd need to buy paste. Make sense?

cheebs - do you caramelise the hazelnuts first and then grind them down for your gianduja?

Lane - a gianduja is usually tempered at a lower temp . . . 27C is what I normally use.

Basically just thoroughly mix the melted chocolate with the hazelnut paste. I've seen some makers in Italy refine/conche them together and others just mix. Personally I just mix well with a stick blender.

Here's a shot of our cremini, as you can see the gianduja is nice and smooth. Any roughness visible in this pic is from the cutting.

such as: when to add the hazelnuts, anything different about tempering, molding, etc

Any tips for making Gianduja at home? I'm interested in getting something like the dark gianduja that Domori makes.

Thank you Rifat. Please message me your email address for me to contact you in person regarding quotes.

Thanks!

We have roaster from 25-5000 tons per hours. Please chech this out to see our mini RoasterMini Easyroast Concept in Use

Hello Dear Omar, I can recomend my roasting machine to you. Actually you dont need rotary roaster beacuse rotary roaster will not help you to roast nuts beacuse of nuts being to fraigle and gentil. I can sugget you hot air roasting with belt layer roasters. Please see our web site www.sevvalmakine.com

Clay - Omar seems to be talking only about roasting nuts, so I think he'll be fine with either a fluid bed or a drum. But this brings up a point I was wondering about: if a drum roaster at typical speeds is too rough for cacao beans, wouldn't a fluid bed roaster be a disaster? It seems like it would make a complete mess of the beans, but you may have heard differently.

Omar -

I would ask the people at Coffee-Tech their experience with shipping to the UAE. You never know.

With respect to the other machines you are talking about. It is very important to be able to control the speed of the drum. Coffee and nut roasters almost certainly rotate too quickly. Cocoa beans, when roasted are very fragile and if they break in the roaster the small fragments can burn easily. You will need to slow the drum down.

Thank you Michael! TOPER looks amazing. exactly what I'm looking for. hope its not too expensive tho.I'm sending a quotation request today..

Interesting discussin indeed! I bought a large fluid bed dryer 3 years ago with the intent of adding a heater to the airflow. It's in storage right now. Kinda cool to see others are trying the same type of technology.

Omar - one other idea. The nut roasting machines you linked to look like drum roasters. If you are OK with using a drum roaster instead of a fluid bed you might want to also take a look at Toper. They are another Turkish company, and as far as I know they have a good reputation. I know that they also make nut roasters, and I think that they can even build whole plants if you have the need and the budget. ( http://www.toper.com/index.html )

Michael thanks for the feedback, I checked the 428 roasters website, I will contact them for customized machines if I do not find any other alternative.

Clay thank you for the feedback, the thing is I am located in Dubai and I am pretty sure the relationship between israel and the UAE does not allow me to purchase anything from them. The machine I am looking for is for roasting hazelnuts and almonds. I found http://www.nutsroastingmachine.com/eng/index.php?urunler/71-94/

a turkish manufacturer, I will do some more research and let you guys know what I'll finally get.

cheers,

Omar

Omar - check out the roasters from Coffee-Tech (Israel). There are a number of roaster sizes available, up to 90kg , and they incorporate a variety of roasting technologies - and the machines are being used for cocoa roasting in Europe and other places. My contact there is Dan Urieli.

Keep in mind that coffee roasters, as is, are not really suitable for cocoa beans. You need to alter the drum speed (slow them down), and the capacity will be less (how much depends on the roaster design). Also keep in mind that hourly capacities for cocoa will be much lower than for coffee as the roasting times for cocoa are much longer, on average, than for coffee. While a 90kg roaster might be able to manage 4 or more coffee roasts an hour, it might only make one for cocoa.

There is a special offer on Coffee-Tech roasters for ChocolateLife members , so when you get in touch with Dan, let him know that you are a ChocolateLife member.

You are looking for what's called a fluid bed roaster. Some people also call it a Sivetz roaster. They are not as common as drum roasters, except at the industrial level, and I know that in the artisanal coffee industry there is a lot of debate about whether or not they are as good as drum roasters. But that's coffee - for roasting nuts I haven't really heard anything either way. Someone else here may know.

Michael Sivetz passed away earlier this year, and I don't know if his company is still around. I think the son took over but I'm not sure. I did hear that one of the main engineers started his own company, called Heis or 428 Roasters. ( http://428roasters.com ) I think that the largest roaster they make at the moment is 35 kilos, but you can ask them and they might be able to ramp that up for you.

I was wondering If anyone can recommend a good Hot air roasting machine for nuts, with a capacity of 60 - 120 KGS per batch. I checked SELMI but I am looking for a bigger machine.

Thanks,

O
