Chocolate is made from the cacao bean, which comes from the cacao tree, which is a tree that grows in the Amazon rainforest. The process of making chocolate from the cacao bean starts with roasting the beans in order to remove the bitter compounds. The beans are then ground and cooked to produce a hot liquid called cocoa mass. The liquid is then mixed with other ingredients such as sugar, milk, or butter and then poured into a mold. After the chocolate is removed from the mold, it is allowed to cool and harden, which is when it is called chocolate.
