Chocolate molds have MANY uses, you dont have to just pour it solid and pop it out!
First I started with Drizzling a pattern on the mold. I use a disposable pastry bag with a very small tip to make neat controlled lines
(you can use a fork, but it is not as controlled and usually thick and thin in areas)
Tap the mold on the table to make sure that the lines are adhered to the surface of the mold. Not hanging.
