A glaze is defined as a thin, liquid, sweet coating that adds shine and color to pastries. Also used as a protective coating to prevent the fruit on the top of tarts from drying out and/or a soggy pastry crust when a moist filling is used. Apricot jam and red currant jelly are the two most popular ingredients used to glaze fruit tarts. A pastry brush is used to lightly coat the fruit with the glaze.
