Simmering is a cooking technique that involves cooking food at a low temperature for a long period of time. The term 'SIMMER' means to cook food in liquid at a temperature just below the boiling point. Simmering slowly is a method of cooking that allows the flavors of the ingredients to blend together and create a more complex flavor. The term 'STEWED' is often used interchangeably with 'simmered slowly, ' as both involve cooking food in liquid at a low temperature for an extended period of time.
