Simmering is a food preparation technique in which foods are cooked in hot liquids kept just below the boiling point of water (which is 100 °C or 212 °F at average sea level air pressure), but higher than poaching temperature. To keep a pot simmering, one brings it to a boil and then reduces the heat to a point where the formation of bubbles has almost ceased, typically a water temperature of about 94 °C (200 °F) at sea level.
