Melting chocolate to harden it is a crucial process in chocolate making, known as tempering. Tempering gives chocolate its glossy appearance, smooth texture, and satisfying snap when broken. It involves heating and cooling the chocolate to create a stable crystal structure that sets the chocolate’s texture and appearance. In this article, we will delve into the world of chocolate tempering, exploring the reasons behind melting chocolate to harden it, the different methods of tempering, and the techniques to achieve perfectly tempered chocolate.
Understanding Chocolate Tempering
Chocolate tempering is a complex process that requires a deep understanding of the chocolate’s crystal structure. Chocolate is composed of cocoa butter, sugar, and sometimes milk. The cocoa butter in chocolate can form different crystal structures, which affect the chocolate’s texture and appearance. There are six different crystal forms that cocoa butter can take, but only one of them, known as the beta crystal, gives chocolate its desirable properties. The beta crystal structure is responsible for the chocolate’s glossy appearance, smooth texture, and satisfying snap.
The Importance of Tempering
Tempering is essential in chocolate making because it allows chocolatiers to control the chocolate’s texture and appearance. Untempered chocolate can be soft, dull, and crumbly, making it unappealing to consumers. Tempered chocolate, on the other hand, has a smooth, glossy appearance and a satisfying snap when broken. Tempering also helps to prevent the chocolate from blooming, which is the formation of a white, chalky coating on the surface of the chocolate. Blooming occurs when the chocolate is not tempered properly, causing the cocoa butter to migrate to the surface and form crystals.
Methods of Tempering
There are several methods of tempering chocolate, including the tabling method, the seeding method, and the machine method. The tabling method involves melting the chocolate to around 105°F to 115°F (40°C to 46°C), then cooling it to around 82°F to 86°F (28°C to 30°C) on a cool surface, such as a marble or granite countertop. The seeding method involves adding a small amount of already tempered chocolate to the melted chocolate, then stirring and cooling it to the desired temperature.
