Chocolate making: Things I learned in my early months

I would say Hans Brunner gets my vote for 3D if you can get them. 

 

I’m sure there is a HB bonbon mold or two in my vast collection but not bought new. 

 

Chocolate World makes excellent bar and bonbon molds, Cabrallon as well, the Cacao Barry molds are good but not sure of the new material yet and they aren’t see through. 

 

Agree with @curls  about some of the other Italian molds - fussy and thin.

 

Chocolat-Chocolat has CW1612 and CW1936

 

Oh yeah - I love the JVK molds I have but it was a challenge to get them.

 

 

Kerry, how do you think the JVK egg molds compare to those from Hans Brunner?  Particularly with regard to where the seam halves come together?  For better or for worse I have a feeling at least with regard to chocolate molds one gets pretty much what one pays for and the JVK are a lot less expensive.

Another batch of bars:

These looked better in real life than in the picture.  If they were all like this I wouldn't complain.  Too much.

Four dozen bars wrapped and ready for this morning's holiday party at work.  Copper are dark, blue are milk.

Nice wrapping! Any inclusions or flavors in your bars? I am thinking about doing some bars for the first time and looking for ideas.

Thank you.  No inclusions or flavors.  The wrapping materials are from Foilman.  I chose a stock size but they can cut foil to order.  The sheets are paper backed silver foil in a range of colors.

That foil is a very interesting idea. I looked at the Foilman site and did not see the thickness of the paper-backed foil. Could you describe approximately how thick it feels? How does it compare to regular foil (such as Reynold's)? I'm looking for something to cover chocolates in a box, and because I'm dealing with a custom size, regular candy pads won't fit. I would need something fairly rigid, or at least something that would not bend easily.

I measure the thickness of the Foilman foil to be 3 mils.  There is no way I could describe how thick that feels.

Life got better when I stopped trying to scrape moulds with a regular palette knife.  I found we had two Japanese okomoniyaki spatulas from Japanese cooking which were perfect!

@anonymouse thanks, this is a very useful post for me, as I am also trying to learn this. When you say "palette knife", what do you mean? Are you referring to a palette knife that painters/artists use? These come in a lot of different shapes and sizes, which one did you use before you switched to a okonomiyaki spatula? Also, I suppose that you use okonomiyaki just because you already had it, so you did not need to get anything else, right? There is no need to search for okonomiyaki specifically, I can get a "regular" scraping spatula for chocolate, right?

What is the density of melted, tempered chocolate?  (Yes, I know, I could measure it myself.)

You did not specify which kind of chocolate and at what temperature.

If I had a cubic meter and a swimming pool.  What I do have is a reference librarian.

 

@teonzo intentionally I did not specify what kind of chocolate, however I assumed "melted, tempered chocolate" denoted a fairly narrow range of temperature.  If makes it easier, just tell me the density of 72 percent dark at 32C.

If we want to be precise then we should specify everything! Even altitude and atmospheric pressure!

I just looked in my Minifie book, no data on chocolate density whatsoever.

I gave a look at Wolfram Alpha too, expecting to find a detailed multidimensional graph that would give the answer for all possible combinations. Nothing! I'm supremely disappointed!

This is really funny, since the only chocolate I have at home is a 72% dark, today I baked some meringues which I was planning to dip in chocolate in the next days. So I am in the position to answer to this question without much hassle when I'll finish those meringues. But before I need to bake other batches (I can't stop eating chocolate dipped meringues), one of them will be an experimental dried porcini meringue (I'm serious about this).

Unfortunately I did not come up with a good answer for the density at work.  The reason for the question is to calculate how much chocolate I need to melt to fill a mold.  The mold is a hollow mold, not solid.  I measure the volume of the mold to be 4,276 ml.

 

Thoughts?

 

Related to this there is a complication that the mold does sit flat.  Not even close.  I need to prop up the corners somehow to make it level.  I have a ring stand and clamps but given the size of the mold I think I need something more industrial, like tomato cans.  Or lower tech like bath towels.

I have bags of Bomba, Basmati, and Bineshii.  Not to mention Tamaki, Carnaroli, and Arborio.  But not a big enough pan.

 

No, I take that back!  I measured.  One pan would just fit the mold by a fraction of an inch!  But we're talking about an awful lot of rice.  I may try setting the mold in the pan and see how level it works out.  But not tonight.

 

Thanks for the idea!

Some questions.

Why do you need to fill it completely with chocolate? If you need a hollow piece, then there is no need to fill a big mold completely with chocolate. If you need a full solid chocolate figure that big (4 liters) then you'll face hell with latent heat of crystallization.

Why do you need to know the exact chocolate weight you need to fill the mold? It's always better to melt more chocolate and being sure (some chocolate always goes wasted during any passage), the exceeding chocolate will be re-used in another way. Unless you are planning to make some expensive one-of-a-kind chocolate with the melangeur. If you are planning in making blueberry chocolate or similars then it's totally understandable you don't want to make more considering the costs, but in this case knowing the density of melted tempered chocolate would not help you, since the density would be different and depend on what ingredients you use.

It's easier to help you if you explain your project. Unless it's a secret and you risk to find a Sith Lord at your door, of course.

Most manufacturers of molds provide a weight in grams for what a cavity will hold. I read somewhere (can't recall where) that this figure is calculated by molding milk chocolate in the cavity. I think that even if it's dark chocolate, the figure will be approximately the same. Obviously, if you multiply that figure by the number of cavities (in your case, there is just one), you will arrive at roughly how much chocolate the mold will hold. If you were using a mold with more cavities, you would also need to add extra to allow for the chocolate that lands between the cavities (I allow 40g for each mold for that figure). If you don't have the weight, could you just weigh a ml of chocolate and multiply by 4,276?

Sorry, no secrets intended, at least not from anybody reading here.  The mold is a Brunner SE-0110-G-L:

https://www.brunnershop.com/en/Spinning-Moulds/Eggs/Smooth-style/Egg-smooth-style-oxid-33.html

 

I had purchased Cacao Barry Tanzanie 75% (that I misremembered as 72%) for the application:

https://www.cacao-barry.com/en-US/chocolate-couverture-cocoa/chd-q75taz/tanzanie

 

But I think at least for my first attempt I'll use Felchlin Maracaibo Creole 49%, of which I have a lot:

https://www.felchlin.com/en/product/cacao-maracaibo

 

Good news that the mold half exactly fits in my large steel pan, almost if it were made for it.  Keeping the mold steady problem solved.  No rice harmed in this experiment.

 

But I'm still not sure how full to fill the mold.  Brunner does not say.  Although for their part number SE-0166-G-B they specify the chocolate article weight as 2400 g.

https://www.brunnershop.com/en/Spinning-Moulds/Eggs/Smooth-style/Egg-smooth-style-oxid-10.html

 

The SE-0166-G-B is the same shape as my SE-0110-G-L, and had I not failed geometry I could probably figure this out.  But if we assume an ellipsoid (which I know this isn't quite) the ratio of surface areas would be approximately 0.54 (I think).  Therefore to achieve the same thickness of chocolate I calculate 2400 g x 0.54, or let's say 1200 g.  Does this sound about right?

 

A small complication is I'm not sure I can properly temper 1200 g at one time.  I could try a kg and see what happens.  What think you?

If you can temper a kg then you can add some more melted chocolate to it once it's tempered. The tempered will temper the untempered as long as it's not too hot or too much.

      I've read some older threads on here about keeping your cocoa butter warm in a dehydrator. We picked up a NutriChef PKFD32 which was the closest we could find to a recommended one (2016/2018) and none of our bottles fit. Which had us ask--are people putting their bottles preset in here or are you using cups/transferring and cleaning your bottles over and over? Also if the PKFD32 isn't what we should be using, is there one generally people like now?
       
      We've grown up from cheap airbrushes to the Grex line and we're attempting to get much more serious about our airbrush techniques. It's been long enough. Any thoughts, tips, tricks, or considerations are greatly appreciated.

      Hello everyone!
       
      Id like your advise about freezing bonbons. 
       
      Lets say i would start to freeze my bonbons now in the summer for Christmas. Would they last for such an extended period of time?
      Also using natural colouring, would the colour remain as good when i open them up after a couple of months?
       
      Would be great to hear your thoughts and experiences on the matter  
      Thank you!

      Hey guys!
       
      Ive been having some difficulty with Valhrona Milk 38%. It doesn't seem to temper like any other milk chocolate. 
      I melt the chocolate to 45C and then using the seeding technique i drop the temp down to 30C. 
      When at 30C it seems tempered but after a few minutes i start to see bad tempering results. 
       
      Is there something in particular about this chocolate that i should know about?

      My supplier decided that cocoa butter is now special order so I had to buy a case. And now I have an excessive amount of cocoa butter, anyone need any?  
       
      Cacao Barry cocoa butter pistoles with a best by date of April 2021   $66 for the 3 kg tub or $22 per kg plus shipping.
