Chocolate is a range of products derived from cocoa (cacao), mixed with fat (i.e. cocoa butter and/or plant oils) and finely powdered sugar to produce a solid confection. There are several types of chocolate according to the proportion of cocoa used in a particular formulation. The use of particular name designations is sometimes subject to governmental regulation.
Milk chocolate is solid chocolate made with milk in the form of milk powder, liquid milk, or condensed milk added. In the 1870s, Swiss confectioner Daniel Peter had developed solid milk chocolate using condensed milk; hitherto it had only been available as a drink. The U.S. Government requires a 10% concentration of chocolate liquor. EU regulations specify a minimum of 25% cocoa solids, however an agreement was reached in 2003 that allows milk chocolate in the UK and Ireland to contain only 20% cocoa solids. This type of chocolate must be called “family milk chocolate” elsewhere in the European Union.
