Vodka sauce Vodka sauce Vodka sauce is an American cuisine sauce made from a smooth tomato sauce, vodka, typical Italian herbs and heavy cream, which gives the sauce its distinctive orange coloration. It gained popularity in the 1970s, when a variation won a national recipe contest in Italy, although it may well have been a sauce before its popularization in the 1970s. It is a key ingredient in penne alla vodka. The vodka's function is, ostensibly, to release flavors in the tomato that are normally inaccessible; using alcoholic beverages for this purpose is common in Italian cooking, although usually accomplished with wine.
Cooking oil the recycling industry, used cooking oil recovered from restaurants and food-processing industries (typically from deep fryers or griddles) is called recycled vegetable oil (RVO), used vegetable oil (UVO), waste vegetable oil (WVO), or yellow grease. Yellow grease is used to feed livestock, and to make soap, make-up, clothes, rubber, detergents, and biodiesel fuel. Used cooking oil, besides being converted to biodiesel, can be used directly in modified diesel engines and for heating. Grease traps or interceptors collect fats and oils from kitchen sinks and floor drains which would otherwise clog sewer lines and interfere with septic systems and sewage treatment.
