Chocolate chips or chocolate morsels are small chunks of sweetened chocolate, used as an ingredient in a number of desserts (notably chocolate chip cookies and muffins), in trail mix and less commonly in some breakfast foods such as pancakes. They are often manufactured as teardrop-shaped volumes with flat circular bases; another variety of chocolate chips have the shape of rectangular or square blocks. They are available in various sizes, usually less than 10 millimetres (0.39 in) in diameter.
Origin
Chocolate chips were created with the invention of chocolate chip cookies in 1937 when Ruth Graves Wakefield of the Toll House Inn in the town of Whitman, Massachusetts added cut-up chunks of a semi-sweet Nestlé chocolate bar to a cookie recipe.[1][2] (The Nestlé brand Toll House cookies is named for the inn.) The cookies were a huge success, and Wakefield reached an agreement in 1939 with Nestlé to add her recipe to the chocolate bar's packaging in exchange for a lifetime supply of chocolate. Initially, Nestlé included a small chopping tool with the chocolate bars. In 1941, Nestlé and at least one of its competitors started selling the chocolate in "chip" (or "morsel") form.[3][4]
Chocolate chips can also be melted and used in sauces and other recipes. The chips melt best at temperatures between 104 and 113 °F (40 and 45 °C). The melting process starts at 90 °F (32 °C), when the cocoa butter starts melting in the chips. The cooking temperature must never exceed 115 °F (46 °C) for milk chocolate and white chocolate, or 120 °F (49 °C) for dark chocolate, or the chocolate will burn.
Although convenient, melted chocolate chips are not always recommended as a substitute for baking chocolate. Because most chocolate chips are designed to retain their shape when baking, they contain less cocoa butter than baking chocolate, and so can be more difficult to work with melted.
Availability
Chocolate chips are popular as a baking ingredient in the United States. Originating in the US, the chocolate chip cookie is widely available many parts of the world. Nestlé and the Hershey Company are some producers of chocolate chips.[5][6]
