Boiling vs. Simmering: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 30, 2024
Boiling is heating a liquid until it reaches a temperature where it bubbles and turns to vapor, while simmering is a gentler process where the liquid is kept just below the boiling point.
Key Differences
Boiling involves heating a liquid to 212°F (100°C), where it vigorously bubbles and steams. Simmering, in contrast, occurs at a lower temperature, typically between 180°F and 205°F (82°C - 96°C), where the liquid gently bubbles at the surface, providing a slower cooking process.
When boiling, the rapid movement of the liquid facilitates quick cooking and is ideal for pasta or sterilizing water. Simmering, with its subdued heat, is better suited for delicate foods like sauces or soups, preventing them from breaking down or burning.
Boiling is a vigorous and noisy process, easily observable by the rolling bubbles and steam. Simmering, however, is quieter and identified by small bubbles and less movement, perfect for extracting flavors without overcooking ingredients.
In boiling, the high temperature can cause some foods to fall apart or become tough. Simmering allows flavors to meld and ingredients to cook thoroughly without the harsh impact of boiling.
Boiling is typically a quick method, used in blanching or cooking foods that can withstand high heat. Simmering is a slower technique, ideal for stews, braises, and stocks, where flavors develop over time.
