What is the Difference Between Simmer and Boil?

The main difference between simmering and boiling lies in the temperature and the movement of the liquid. Here are the key differences:

• Temperature: Boiling water reaches a temperature of 212ºF (100ºC), while simmering water is between 180-190ºF (82-88ºC).
• Bubbles: Boiling water has large bubbles at the bottom of the pot that quickly rise to break the surface of the liquid. In contrast, simmering water has slow, gentle, and small bubbles.
• Purpose: Boiling water is often used for making pasta, blanching vegetables, and cooking food at a high temperature. Simmering is used for soups, broths, and stews, as it helps cook the ingredients slowly and develop a rich flavor.

To convert a boil to a simmer, you should bring the water to a full, rolling boil and then reduce the heat to maintain the gentler bubbles. Understanding the difference between simmering and boiling is essential for achieving the desired flavors and textures in various recipes.

Comparative Table: Simmer vs Boil
