Taste, smell and color are changed many times throughout the process. White chocolate does not use the ground cacao bean entirely. Only the cacao butter and vanilla flavoring. The more milk added, the more sugar added, which means the sweeter the chocolate taste. Bakers' chocolate has the least amount of sugar.
Milk chocolate has a less bitter taste that semisweet or dark chocolate.
Chocolate used to be considered only a delicacy to be enjoyed by the rich. It was also imported to our country from the more central and southern continents. It originally was available only to the royalty in Europe. Have students research exactly how that item is manufactured. Have students sample various types of chocolate and make predictions about what ingredient is dominant.
