Boiling vs. Simmering: Why It Matters for Flavor
Boiling is a high-heat cooking method that can cause rapid water evaporation and toughen proteins. In contrast, simmering is a gentle, low-heat method that allows for even cooking and flavor development. Simmering also reduces the risk of scorching.
Why Simmering is Preferred
Simmering encourages the release of flavors from the ingredients without overcooking them. The gentle heat ensures that ingredients retain their texture and nutrients. It promotes gradual infusion of flavor into the liquid.
When Boiling Might Be Necessary (and How to Avoid It)
In rare cases, you might briefly boil liquid to dissolve a bouillon cube or quickly cook a small amount of pasta. However, it's generally best to avoid prolonged boiling. Consider cooking pasta separately to avoid a starchy soup.
Simmering Technique: Lentil Soup Example
1. In a large pot, combine the bone broth, mirepoix, garlic, lentils, diced tomatoes, bay leaf, and thyme sprigs.
2. Bring the mixture to a gentle simmer over medium heat. Then reduce the heat to low.
3. Cover the pot and simmer for 1 hour to 1 hour 15 minutes, or until the lentils are tender.
4. Remove the bay leaf and thyme sprigs.
5. Season with salt and pepper to taste. Stir in the lemon juice.
6. Ladle into bowls and serve.
Avoiding Over-Boiling
If your soup begins to boil, immediately reduce the heat to the lowest setting. Stir occasionally to prevent sticking. The goal is to maintain a gentle, bubbling simmer.

FAQ
-
How do I know if my soup is simmering and not boiling?
Simmering is characterized by small, gentle bubbles that rise to the surface occasionally. Boiling involves large, rapid bubbles and vigorous movement. -
Can I add ingredients during the simmering process?
Yes! Adding ingredients at different times during simmering can create layers of flavor. Heartier vegetables like potatoes or carrots should be added earlier, while delicate herbs or leafy greens should be added towards the end. -
What happens if I boil my soup by accident?
If you accidentally boil your soup, reduce the heat immediately and check for scorching on the bottom of the pot. Taste the soup to see if the flavors are still balanced. You might need to add more liquid to compensate for evaporation.
