Indian reductions are a type of cooking technique used in some parts of India. It is a process of cooking food in a spiced oil or gravy over a low, steady heat. This slow cooking process helps to soften and tenderize the food, and to develop flavor. This type of cooking also brings out the natural flavors of the ingredients being cooked. For example, if you cook beef or chicken with onions, garlic, spices, and herbs in a reduction, the meat will become very flavorful and juicy.
