Makes total sense, dipping right away saves every last drop. Do you use compound chocolate or regular bar chocolate, and about how long do they take to set in the fridge? Do you add the sprinkles right after dipping so they stick, or wait a minute for the coating to firm up a little?
It only took about 15 minutes for it to harden completely. I added the sprinkles directly after dipping.
Fifteen minutes is quicker than I expected. Are you using milk or dark chocolate for the coating, and does the margarine make it glossy enough on its own? Do you ever add a splash of oil if it gets too thick? One more thing, do they release cleanly from the cup molds or do you line them first?
