Feeling a little gelty

#1

My son came up with the idea, "Let’s use the Glowforge to make Chanukah gelt! (chocolate coins). He and his sister each designed one side.

Notes:

  • I don’t know how to temper chocolate, so it’s dully and scratchy instead of pretty and shiny
  • While I’ve cut and engraved chocolate directly before, rolling it into thin sheets is a pain & I wanted to try a different technique
  • First time I’ve ever used the silicone mold; it was effortless
  • I poured the chocolate into both sides, then just smushed them together
  • Instead of using trace, I took pictures of the original images on my phone and edited them in illustrator (DADDY YOU HAVE TO MAKE THE TOP SHORTER I MADE IT TOO LONG!)
  • It was delicious. :slight_smile:

Great to see the GF being used as part of the process.


#3

Great to see the kids’ imagination coming to reality.

Nice. As the saying goes, gelt is the welt. Chocolate gelt doubly so, I say.

Now… how do you line your molds with gold foil first for true authenticity? :wink:

#5

Well, of course! You could make a matching embossed piece to fit the gold foil into the mold before pouring the chocolate.


#6

Ya know, from the right angle, never noticed how a Menorah looks an awful lot like a B52 bomber.

What a fun project for the whole family to get involved with! (You need to put your children on the design team, they’re very creative thinkers!) :smile:


#8

That is awesome. I love the silicone idea!


#9

Both involve lots of fire… Yup… The ancient Maccabees predicted and influenced modern warfare.

It’s always fun to see other people’s skills blind-spots :slight_smile: Tempering chocolate is one of those basic baking skills. Juxtaposed with a guy who is super-skilled in all sorts of arcane technology and business and other hobby stuff. :slight_smile: It’s like a skip moment - whoa, what do you mean you don’t know how to do something, you know everything :smile: Makes you more approachable - not just the CEO of a huge new startup. :glowforge: Happy Hanukkah!


#11

If not knowing something is the defining characteristic, have never met anyone that wasn’t “approachable”. Just that quite a few pretend to know everything.:smirk:

Shucks, I must be one of the most cuddly people on the planet.

@Dan How-to temper chocolate: heat the choloate up to 43°C then let it cool down to 21°C (you can put in some unmeltet chocolate to speed up the cooling process - max 1/3!) then heat it up again to 30°C (Milk Chcolate) :yum:


#13

Is an infrared thermometer good enough for checking the temperature?


#14

I would guess so… we started with a “meat” Thermometer - nowdays we have a temper device
(we are not very good in cooking nor backing - but pralines are ours :yum:


#15

LOL. Go get a candy thermometer! It’ll also make making fudge a lot easier.

The immersion circulator can do this evidently very well. Will have to try it some time.

Happy Chanuka!

This depends on your method. If you are starting from pre-tempered chocolate (like a candy bar) then it is a very easy and basic skill… see below. If you are starting from a completely melted batch of chocolate, it is a very difficult skill, almost an art… if you are tabling as opposed to using a machine.

If you search tempering on YouTube seeding is the predominant method of tempering. Since I am making batches of chocolate from scratch, I don’t have any pre-tempered to seed with. Thus far I’ve tempered by tabling, but I plan to make a tempering bowl soon.

I think you are referring to Sous Vide. The thing that sous vide is good at is maintaining a specific temperature for a long period of time. Putting your chocolate into a bag and into the water can work, but to ensure that all of your chocolate is at the correct temperature to temper properly, you would have to leave it in for a very long time. Part of tempering is agitation, and unfortunately it is very difficult to agitate the chocolate while it is under water. I’ve attempted it twice now, and each time I have lost at least one bag to seizing… and I finally figured out why. I wasn’t using vacuum sealed bags, and since there was air (and therefore moisture) inside the bag, it condensed in the empty spaces above the chocolate, then as I agitated it started to mix in and the bag seized. This last time I figured this out on the first bag, so with the other bags I didn’t agitate at all, and I cut them open below the chocolate line. This saved the chocolate, but the temper was horrible.

I do intend to make a tempering bowl. I’m going to make an acrylic box with two holes in the top. One is for the sous vide and the other is for an aluminium bowl. Fill the box with water, drop in the bowl and the sous vide and I have a completely temperature controlled bowl. For now I will hand stir, but eventually I might add a motor system to spin the bowl against a fixed spatula.

Oh, and when I tempered by tabling, I used an infrared thermometer and it works very well.

I’m just going to consider you the new Willy Wonka.

Thanks for the great info!

The acrylic works pretty well for a stamp. I need to try it. I didn’t have any acetal ProofGrade in my box of goodies to try out, but I have sourced some now and next week will try it out. Stamps for cookies and leather will be so cool with this.

Thanks. I’ve been researching and practicing off and on for the past few years.
