A turntable makes it easier to decorate all sides of a cake and to smooth the frosting evenly. For the average cake, an inexpensive plastic turntable such as a lazy Susan, sold in housewares stores and supermarkets, works as well as a professional heavyweight footed variety. To bring the level up to the desired height, place the turntable on a large inverted cake pan. A turntable can be transformed into an elegant cake server by placing a large serving plate or piece of marble on top. Heavyweight turntables are available from cake decorating and baking supply stores. The most stable and smoothest turning model is from Fat Daddio’s.
