I cooked some food cubes.
The recipe comes from The Star Trek Cookbook by Chelsea Monroe-Cassel. My first time but I’m going to make more. This batch has orange extract. I will need to increase the amount of extract.
UPDATE: I made blue lemon this time.
Chelsea did an AMA with us back in the Old Place when the book came out. She seemed cool, and fairly knowledgeable about, y'know, cooking.
I'd be curious to hear how the recipes turn out for you.
I need more flavor extract like I said before. Shaping the cube is the hardest part.
Why not make a slab then cut cubes out of it?
You are spreading out a thin layer of dough and is rolled into small balls that get shaped into cubes. Unless you want super think cubes and less in a batch. The recipe estimates you get 2 dozen in a single batch.
EDIT: You want a somewhat dense 3D shape.
I think if I were to make the attempt at this, I'd have used a silicone ice cube tray. I've got one in my silicone moulds. Not as fun as the Starfleet delta, but pretty good at making things cube shaped.
Make a big flat pancake of batter and use a cookie-cutter?
