Simmer is a cooking technique that involves heating a liquid just below its boiling point. This method allows food to cook gently, which helps to develop flavors without the risk of burning or overcooking. Simmering is commonly used for soups, stews, and sauces, where ingredients can meld together harmoniously. During simmering, small bubbles form and rise to the surface, but the liquid does not reach a full boil. This technique is often preferred for cooking delicate items like fish or vegetables, as it preserves their texture and nutrients. Proper simmering can enhance the overall taste of a dish.
