  1. Post 24 of that thread gives the answer from Chef Greweling himself, which corroborates what his student Tiny said.

    I agree with gap. I don't think you can know for sure unless you always buy from the same supplier (and assuming that supplier doesn't repackage things from their upstream supplier).

    L'epicerie actually asked their suppliers about their composition. It appears 'dextrose' by definition will be pretty much the same, but 'atomized glucose' may depend on who you buy it from. Chef Greweling said that as well. My mention of L'Epicerie is an acknowledgment of data source (def. not an endorsement).

    One of their supplier was the following

    Dextrose:

    Carbohydrate Composition (Dry Basis):

    Regulatory Data:

    Dextrose, %

    99.7

    United States

    Other Saccharides,%

    0.3

    Corn Syrup Solids:

    Dextrose, %

    7.0

    Maltose, %

    7.0

    Regulatory Data:

    Trisaccharides, %

    8.0

    United States

    Higher Saccharides, %

    78.0

    For another of L'Epicerie's suppliers, the information was the following

    Dextrose: (a) Dextrose monohydrate is purified and crystallized D-glucose containing one molecule of water of crystallization with each molecule of D-glucose. (b) The food shall meet the following specifications: (1) The total solids content is not less than 90.0 percent mass/mass (m/m), and the reducing sugar content (dextrose equivalent), expressed as D-glucose, is not less than 99.5 percent m/m calculated on a dry basis.

    Corn Syrup Solids:(a) Dried glucose sirup is glucose sirup from which the water has been partially removed and conforms to the specifications of Sec. 168.120, except that: (1) The total solids content is not less than 90.0 percent m/m when the reducing sugar content (dextrose equivalent), expressed as D- glucose, is not less than 88.0 percent m/m, calculated on a dry basis; or (2) The total solids content is not less than 93.0 percent m/m when the reducing sugar content, (dextrose equivalent) expressed as D- glucose, is less than 88.0 percent m/m, calculated on a dry basis.

  2. chocolate purchasing question, really gathering opinions.

    I can buy Callebaut in blocks at a local store for $3.50 a pound for the 11 lb block.

    I could buy Callebaut callets for around $5.50 a pound in the 22 lb bags, plus shipping.

    For those of you who use callets (or feves, pistoles, whatever): is it worth it?

    I don't have a business to run, but for one batch of chocolates (~400 or so) this would run about $25-30 or so extra in costs per batch.

  3. maybe this is the Materials engineer in me talking, but all phase diagrams are affected by pressure to some degree. The most commonly known being Carbon, where heat and pressure turn it into diamond and you can substitute one for another. It's just that for liquids to gasses dP/dT is usually much larger than for solid-solid phase transitions.

    That is, the effect at 'altitude' is still there, just too small to measure.

  4. hey do you mind sharing your coloring technique?

    On your website, there's a 1/2 green, 1/2 yellow with chocolate drizzle.

    there's a red, white, and blue . If it is OK, do you mind mentioning how you do those?

  5. Thanks Steve for your advice! It is amazing how one can always pick up a new tip!!! :biggrin:

    The acetate method is actually not too messy. Liek a transfer sheet that comes off clean-from the magnetic mold. Yes, you scrape on top of the acetate which is ON top of the chocolate. If you put too much extra choc it will get on the sides otherwise it just comes off the end of the mold at the last place you swipe. Even if it does get on the sides a bit it is easy to scrape off as the mold is sitting on the counter just goe down the side. The extra bit of choc can be reused.

    Next I will try Steve's method.

    I just remembered last night that Schneich once gave a link to a utube video from some chocolate exhibition he was at and I think the demonstrator used this acetate closing method. Here !! I just found it!

    great memory! And thanks for the video.

    I still have to say it looks messier this way.

    In this method in the video, it looks like the chocolate gets all over the table from the mold when it is set down. Then chocolate gets on the bottom of the mold from the table. Then you "track" chocolate even more places when you put the mold down to set. And the excess off the side when you scrape. Plus the acetate when you take it off and set it down somewhere. I was also surprised to see the guy wasn't using gloves but maybe that is a difference between American and Euro production.

    The other way, the chocolate only goes from the mold to the melter (mostly) with nothing on the table or even your hands.

  6. okay! I tried the acetate and transfer method but on closing bars, as I wanted to make bars. But it should be exactly the same with closing molded chocolates. It is brilliant. I did half the mold with a transfer sheet-although I am almost ashamed to admit that I am not a fan of transfers and artificial colors (I know I am the odd man out-sorry) but it was fun using anyway. On the other half I used a piping bag as I don't have acetate I have to get. Both worked really nicely-perfect finish.

    Method:

    After I filled the cavities of the 50g bars and knocked out air bubbles I added a row of extra melted tempered choc.  :rolleyes: Becasue I did half a mold I put the extra chocolate in the center of the mold. I took the mold to my counter and placed it on baking paper. I then lay the transfer sheet on top of the half I was working on and with a good triangular spatula swiped from center to edge so the extra chocolate came off onto the baking paper and the transfer adhered nicely to the chocolate. I waited till it hardened a bit and then did the other half with the acetate(piping bag in this case!). Both came out lovely.

    For picky finishing perfection freaks, this is a good method!

    thanks for the extra description! ONe question, this seems messier to me than the other way. That is, your sheet (or bag) will have all sorts of chocolate on it ,and acetate is kind of floppy. It seems like it would get everywhere. Also, it seems like when you use the spatula on the acetate (which is on the chocolate?) it would leak over the sides of the mold.

  7. It's a little more time consuming, but if you want you can use a guitar sheet or acetate to cap your chocolates. It makes for the most 'perfect' finish and also allows you to have more filling and a less thick base. You ladle chocolate on just one edge of the mould, put the plastic so that it covers the open surface of the mould and then, using a squeegee or triangle spatula, pull the chocolate across to the other side. Not sure how understandable that explanation is...  :hmmm:

    That leaves a slight dimple though so if you're really fussy you can go over it twice and then it becomes really really flat.

    If you ever get a chance, take a few pictures next time you use this techinque. Sounds interesting, but i'm still a little confused.

    Luis

    I too would love some pics. Or even some more details - the spatula is in contact with the mold, and the acetate comes after? I am not sure how the acetate come in to it.

  8. As a last resort, you can freeze your molds. They probably pop out after that (and a lot of banging). To reduce sugar bloom after this, you use a dehumidifier or work in a dry environment. And cover with plastic wrap immediately. They won't be as nice, but they'll probably be good enough for personal use.

    But, everybody else is correct, it's best to improve the technique so you don't have the problem at all.

  9. My technique with the pyramid molds is to slam them on the counter a few times, then put on the vibrating table. (There's a thread on eGullet about making your own, cheaper than ordering from ChefRubber.)

    I still get a few with bad corners, but that takes care of most of them. My couveture (Cluizel) is pretty fluid to start with, and I'll try to do that mold early in my sequence, since I know it's fiddly (by contrast, I tend to do my domes last, since they're least prone to air bubbles). The toothpick thing sounds way too time consuming for high volume production...

    Based on advice from thsi forum, I bought a dental vibrator from ebay, which I think is what you use too. $50 or so.

    I also do my production like Tammy with regards to difficulty of molds - start with Pyramid and Cherry and squares, end with domes and hearts.

    The kugelhopfs though are still the worst.

  10. Just to add one thing if you buy from JB Prince. (and Tammy can add or contradict).

    I've found JB Prince to have great customer service. I request for them to tell me if it's going to be delayed for whatever reason, and they always do. Once I got a wrong mold (it was labeled wrong). They had UPS pick up the wrong mold and they shipped the correct one immediately, without even shipping cost to me.

  11. Some moldy bonbons were just brought to my attention.  :shock:   Oooops.  I've only been playing with molded chocolates (mostly at home) for about 2 years, but I've never had moldy ones before, so I'd appreciate any input on what might have gone wrong. 

    Fuzzy bonbons is sooo not 'luxury hotel'!

    in his book, Frederic Bau says this can happen if the ganache is not properly crystallized or if it is too wet when backed. He says the "free" water absorbs into the chocolate, shrinking the ganache and leaving a tiny space which is an ideal hothouse for bacteria and mold.

    Not saying this is it, just saying this is one source of mold according to an expert. I guess you could get the same effect if you backed the molds but didn't vibrate to ensure a good contact.

  12. like marmalade, I 'cheat' and put them in the fridge. I run a dehumidifier (from ebay) to prevent sugar bloom.

    I also want to thank the egullet'er who suggested the 'ice cube' technique, it works great for me!

  13. Microsoft Excel.

    I record the ratios of ingredients. I record the required ganache weight for a particular mold type. Then I can scale to any number of molds or mold types with not too much waste in material. Excel prevents calculation errors.

    At least that's the theory. I still waste some. But every time I do it, I waste less.
