You can make hemispherical chocolates with a handmade chocolate mold. This is a hard-type chocolate mold used by professional chocolatiers around the world. We will ship it out the same day! You can still make it in time for Valentine's Day! When removing the chocolate from the mold, tap the edge of the mold against a hard surface such as a table or a pastry board covered with a cloth. The gram indication in the size description is an approximate guide per piece. Proper temperature control (tempering) is the key to making good chocolate!
