Is soup bad when it bubbles?

It depends on the kind of bubbles you're seeing! Here's a breakdown:

Good Bubbles:

* Gentle simmering: This is normal and desirable for most soups. It helps to extract flavor from ingredients and cook them evenly.

* Bubbles from ingredients: Some ingredients, like beans or lentils, naturally release gas during cooking, creating bubbles. These are harmless.

Bad Bubbles:

* Excessive foaming or boiling over: This can happen if the heat is too high or if there are too many proteins in the soup (like a lot of milk).

* Bubbles with an unpleasant smell: This could indicate something is burning or spoiling.

* Bubbles accompanied by unusual color changes: This could mean something is going wrong with the cooking process.

What to Do:

* If the soup is gently simmering with normal bubbles: Enjoy!

* If the soup is boiling over: Reduce heat and/or skim off the foam with a spoon.

* If the soup smells bad or looks unusual: It's best to discard it.

In general, if your soup is bubbling gently and smells delicious, it's perfectly fine to eat!
