Im actually gathering stuff for my next batch now.
I usually use some regular frozen foods like Mysis shrimp, enriched brine, blood worms, cyclopeeze and such, along with smaller items like coral foods, baby brine, rotifers and such.
Then hit up the asian market for whatever is cheap like, whiting fillets, scallops, shrimp, squid, fish eggs(used in sushi)
I take it all and thaw it out, blend it up and mix it all together. Throw in some pellet foods, and ground nori and refreeze it in 1gal bags filled to be about 1/4" thick.
There is no real science to it, just whatever I can find when Im making the stuff. Just be sure to blend the fresh foods to a good size and leave shell and skin on. I usually blend it all to be small enough for all the fish to eat, then remove 3/4 of it and blend the rest to a paste.
I dont use any fillers or add any water to it so smaller bits of food actually have more food in them.
Been doing this for years and never had any problems at all except for much fatter fish and happy corals.
EDIT : oh and adding stuff like garlic extract and vitamins is doable as well, but I usually dont bother.

I tried this and its a serious PITA to get the cubes out of the egg crate without letting it melt a bit and then its a huge PITA to clean up and alot of food gets wasted.
Freezer bag and a hammer work just fine
