What is the process of simmering and how does it differ from boiling?

Simmering is a cooking technique where food is cooked gently in liquid at a low temperature, just below boiling. This allows flavors to meld and ingredients to cook slowly. Boiling, on the other hand, is when liquid reaches its highest temperature and bubbles vigorously. Simmering is a slower and more gentle method of cooking compared to boiling.
