Cake or syringe using a coupler. The bag or syringe is partially filled with icing which is sometimes colored. Using different piping tips and various techniques, a cake decorator can make many different designs. Basic decorating tips include open star, closed star, basketweave, round, drop flower, leaf, multi, petal, and specialty tips. An embossing mat is used to create embossed effects. A cake turntable that cakes are spun upon may be used in cake decoration. Royal icing, marzipan (or a less sweet version, known as almond paste), fondant icing (also known as sugarpaste), and buttercream are used as covering icings and
Induction cooking 24 kHz. Such high frequencies are not feasible with inexpensive power semiconductors; in 1973 the silicon-controlled rectifiers used were limited to no more than 40 kHz. Even a thin layer of copper on the bottom of a steel cooking vessel will shield the steel from the magnetic field and make it unusable for an induction top. Some additional heat is created by hysteresis losses in the pot due to its ferromagnetic nature, but this creates less than ten percent of the total heat generated. New types of power semiconductors and low-loss coil designs have made an all-metal cooker possible. Panasonic
