Sugar crust

Sugar crust, in chocolate confectionery, is a method to prepare liquid (often liqueur) filled chocolates.

The solid sugar crust is formed from a supersaturated sugar solution with a filling of choice. The crust completely seals the filling, allowing it to be coated with a layer of chocolate in a process called enrobing.

Preparation of sugar encrusted liqueurs

Sugar crusts are formed by pouring filling into moulds prepared of starch (referred as starch moulds). The moulds are about room temperature. The surface of the liquid that is exposed to the air is dusted with starch. After approximately two hours, crusts form. These crusts are flipped and left to stand in starch for twenty-four hours. After standing for this period of time, the resulting shells are ready to be enrobed in chocolate.
