Microwave tempering
Posted in: Tech Help, Tips, Tricks, Techniques
Thanks Jim.
I tried on milk chocolate and it worked too.
But if I have a 90.5F holding tank with a dispenser, never let it cool down or empty. Would it be fine?

If you can keep (dark) chocolate at that 90-91F. temperature, you are fine, but sometimes reality intervenes: If, for example, you are using chocolate left over from a previous session, it is very unlikely still to be in temper and must therefore be raised to high enough a temp to melt out all the crystals. I use your method (of very careful melting-though I do it over a water bath and not in a microwave) if I am doing a small amount (e.g., for a ganache or for decorating finished pieces), but it is very difficult to melt a large amount (e.g., for dipping pieces or filling molds) and keep the temp within the final working range.
I have this question bothering me for a long time and am happy to find this forum. I hope my question can be answered.
I saw the microwave tempering process-starting with pre-tempered wafer, heat at different interval in microwave. Make sure it is melted but less than 91F. Than the chocolate is tempered. I tried it and it works! So in this logic, I can just have a warmer at constant 90.5Fto melt the chocolate and have tempered chocolate all the time?
If this makes sense, why do I need temper machine, as long as it starts with tempered chocolate? ( I know it can not make sense but what makes it nonsense?)
Thanks!

Hello everyone! I'm working on a specialty cordial recipe and have a couple questions. Has anyone used from scratch brandied cherries in their cordials vs jarred maraschinos? Have you had any trouble with additional water content? Also, is there any need to worry about refrigeration when using "fresh" cherries or is the sugar/alcohol content still high enough not to be a worry? l appreciate any thoughts!
I think I do.. but I am worried about making a bad decision..
but more and more I think that to stop selling truffles by unit is the way to go.. I will only offer them in mixed boxes, and I am looking at doing some wine pairings with a local wine shop and create custom truffles that will be sold in pre packaged boxes of 2 and 4.
basically I wanted to see if anyone else went this route.. and do not offer truffles traditionally in a case..
I think you should concentrate on what is selling. Sounds like you know what you should do:)
I was looking for comments and opinions and comments.. not cocoa beans LOL

Hi, About 6 weeks ago I opened up a chocolate kiosk within a very popular candy store, now what I taught would be smooth sailing has proven to be a real challenge.. I am restricted to 160sq/ft production and retail space.
I am offering a bit of everything.. molded products, truffles, dipped products and a whole lot of chocolate bars
Now I am debating what to do with my truffles.. I think my price point is a bit too high but I am also debating how I will continue to sell them.. right now I have a selection of 21 truffles in a non refrigerated display case that sits on my counter.. I don't sell that many, people coming in are not looking to buy chocolates in the first place so i sell only a few here and there, they are more attracted to my fancy and off the wall chocolate bar flavors.. I am wondering if I would not just be better off to eliminate the case and pack the truffles in mixed chocolate boxes and stop selling by unit.. and gain back some counter space for faster selling items.
Anyone else has dropped selling truffles by the unit and just went pre packaged ? If I had a ton of space i would continue but right now the amount I am selling anyways doesn't feel like it is making good use of that counter.. comments ? ideas ?
Hi Clay, probably too busy, but if you could give me the contact of serious peru awesome. many thanks
Hi Clay,
Hi Clay, thanks for your help and expertise, could you tell me what cost has this machine Peru?
Mariano:
I would not buy directly from China unless you are prepared, immediately upon arrival, to examine all of the electrics and electronics and completely re-wire the machine. I would also make sure to ask what material the blades and the inner surfaces of the machine are made of. They have to be made from extremely hard (expensive) steel. Otherwise they will wear down quickly and you will get a lot of metal in the chocolate. Ask what kind of steel and then let me know, I can tell you if it's the right kind.
These are the sorts of details that the Peruvian company I work with takes care of for you. We also work hard to ensure the quality and finish of the welding is good. They are little things - but unless you are prepared to do the work yourself, it makes sense to spend the extra money and have them done for you.
Mariano:
This type machine is called a Universal and it can be used to grind, refine, and conche chocolate.
If you are interested in a machine of this type I work with a supplier down in Peru who can provide them in either 40L or 100L capacities and ship directly to you in Honduras. I have worked with the supplier to make minor modifications on the smaller machine to improve air flow (and therefore conching ability).

Hi all,
anyone know if this machine is good for conching chocolate?
thnks...
For a hobby? not at all.
For commercial purposes - depends on where you live, as the laws are different by country.
Herein lies the importance of effective winnowing - ensuring as much shell as possible is out of the testing stream is helpful in ensuring as much beans as possible pass.
Speaking from the South American perspective, no individual grower I've ever heard of has the capacity or resources to do this testing. and its not necessary as they sell mostly to middlemen who in turn sell to aggregators who turn bulk beans into cheap liquor for cheap nestle and winter products. No individual small producer could be held to account under the current value chain.
I assume the big co-ops in San Martin must cooperate with their US and EU clients, either here on site or there at the destination end, testing finished origin products or they couldn't comply with US / EU regs. The Peruvian Ministry of Agriculture has been concerned about this and actively opposed the latest, stricter EU cadmium regs.
As for Maraon chocolate, we have had our Pure Nacional beans and Fortunato #4 couverture tested in the US and EU and we meet all regs for cadmium content. We are fortunate that our location in the Maraon Canyon has naturally compliant soils!

no sir - rules are rules. the question was do any plantation owners do heavy metals testing, and while there may be one out there, i've yet to meet him. They normally don't have the technical capacity or competency to do so, and frankly it may not be in their best interest to do so even if they could. The responsibility to ensure compliance with the finished product rests with the person offering the finished product, or the person importing the raw material. larger exporters will conduct raw materials testing (pesticides, heavy metals, etc) for customers who are large enough to justify it - but again they're not going to do it for everyone as to be frank it creates a headache for them (a certain amount will fail - and then what? now they've got a pile of rejected beans that they have to find a home for - the more they test the larger the pile is going to be..and frankly they're not selling chocolate, they're selling a component of it, and have no idea at which usage level (i.e. dilution rate) you're going to use it, so they have no idea what level is appropriate for your usage rate..)
The limit is not just a guide.
Australian New Zealand Food Standard in Part 1.4.1 sets Maximum Level for heavy metal contaminants in food product and the maximum level for Cadmium in chocolate is 0.5mg/kg (not 0.5ppm as I have written above).
This is a legaly enforeable limit and applies to all chocolates sold in Australia and New Zealand.
As Sebastian correctly written above cocoa beans from some American countries have very high cadmium content which means that they can be used as a very limited percentage of your recipe.
Many exporters and brand owners will do heavy metals testing, but i've never met a grower who does. S. and C. American soils are heavily volcanic, which in turn translates into the flesh of the bean. Lead - which often is on the shell - is relatively easy to remove and mitigate. Cadmium - which gets incorporated into the flesh to a higher degree than does lead - becomes more difficult to 'wash off', and blending strategies are employed if there are country specific regulations (Japan's another country with high hurdle regulations, for example)
Haigh's have to play by the rules.
In Australia (unlike in many other countries) there is maximum limit of 0.5ppm for Cadmium content in chocolate.
This means that beans from places like Ecuador or Venezuela (which have high Cadmium content) can be used only as a small part of total cocoa liquor in recipes.
I do not know of a single grower that routinely does heavy metal testing.
I am wondering with all the new small bean to bar chocolate makers if any are getting heavy metal testing done. This I am curious about because some makers maybe get a bag or two in from obscure sources and heavy metal testing may not be something that they think they need to do. I know that Haigh's here in Adelaide are very concerned about this aspect and every shipment is evaluated for heavy metals. With their import size as well Australian customs would get on their case about the levels too but with smaller imports they may slip through - at least for a little while until customs catch on.
Is it common practice for plantations to have their soils tested or beans tested before export? I would guess no judging by the fact that Haigh's test everything.
Also I do know that the Australian growers have their soils tested and this was a very important aspect of setting up the plantations.

I have just ordered few mold that are 12-14 gr.
I also think that each piece should be two bites.
You might visit www.chocolateworld.be and look at their enormous selection of molds, most of which have a weight (in grams) for the finished piece provided. You will find many much less than 13g. The first molds I bought, which were Italian, came from a vendor that does not provide weights, and as there was no easy way of judging the size of a finished piece, I ended up with molds that I now think are quite small, say 10g or less, and those who tried my chocolates found them a little too "dainty." Now I look for molds that are around 15g, which offer--for polite people, at least--two bites rather than one. I myself would not go any lower than 12g and my largest is 18g, but quite a few well-known chocolatiers have single-bite pieces in their collections. To state the obvious, to fill an 18-gram shell takes more ganache than you might expect!
Thanks for the comment, what size/weight is common, what size/weight do you use?
13 grams is a small but decent weight. I find making a paper with the dimensions listed helps me to visualize the chocolate.
Could you make a paper/clay/dough/caramel... form with the same size? What do you think about it with a real one in front of you?
is it 1.5CM tall? it seems like those dimensions don't fit the picture. The chocolate in the picture is about as tall as it is wide. 2.5cm tall makes more sense. (I do see where they listed the size on the website) but hey, it could be worth ordering one to test the mold.
Hi,
I want to buy a lot of moulds and on aliexpress.com it a great price.
I just wonder about the size of each piece - it is 2.8*2.8*1.5cm, and 13gr in weight.
Is it a good size for a piece or is it too small?

That does sound like it might be what it is, as it seems to be liquid when warmed and goes hard when cooled. I heard back from the company who have apparently sent out a brand new machine which Is not what I was expecting but great! only wanted to know if they had seen it before. I will use your advice on the new machine and clean it first with oil and sugar, and clean inside the wheels thoroughly too after every batch.
Thanks for the help.
I ran a neutral vegetable oil and white sugar 50/50 when I first got the machine. I think total weight was about 600g. Then discarded the sugar/oil and washed down the grinder. I don't think there's a perfect way of doing it but that's what I did. If you've already run chocolate through it, you've probably done enough "cleaning" and the stone dust should be out by now.
Hi Gap,
Thanks for the reply. I didn't run oil and sugar through it when I got it, I washed everything, but didn't even occur to me to run oil and sugar through it. Does it have to be much of each to 'clean' it? and I will give that a go. I have cleaned off all the horrible black gunge stuff now, and hopefully that was the last of it.
I have been cleaning the wheels by dismantling it, but left the 'grease' stuff on the axles as I assumed that must be there for a reason and would be properly sealed....but I was wrong. I am still waiting to hear back from the company who told me they were going to take one apart to look at it. also got some samples to send to environmental health just in case.
thanks for the advice
Did you "wash" your machine by running oil and sugar through it for a few hours before making chocolate (discard the resulting oil & sugar mixture)? That helps clean off the stone dust/grit that comes with delivery.
Also, between each batch, are you removing the wheels and cleaning the insides of them (say with a cotton bud)?
Hi everyone,
have been using my premier 2ltr wet stone grinder but have run into a potential disaster.
I have only used it 3 times so far and its been brilliant, however on my last run on it some sickly looking dark green/black liquid was coming out from the axle and wheels and running into the delicious chocolate!
Firstly I am unsure what it is, it kind of looks like car grease which is not good.
2nd is it food safe? can I go ahead and taste the chocolate I made or should I condemn the entire batch?
3rd - is this normal? has anyone else come across this problem before?
I have attached some photos to give you a better idea of what I am up against. I have also contacted the company I purchased the machine from and await their response.
any help much appreciated
James

I meant that we have a supplying branch in Turkey. We ship already tested cocoa to our partners in Turkey for sale. Our main factory is based in Kumba,Cameroon.
