When chunks of meat, seafood or vegetables are slow-simmered in a flavorful liquid brew, the result is a warming, comforting dish called a stew. Slow, moist cooking is the best way to tenderize tough cuts of meat (which happen to also be the most flavorful). Stews are also a great way to use up leftovers. And speaking of leftovers, most stews are more flavorful the next day.
