Do you put the onion skin in french soup?

Here's why:

* Flavor: Onion skin can impart a slightly bitter and earthy flavor that isn't typically desired in French soup.

* Texture: The skin is tough and fibrous, which would create an unpleasant texture in the soup.

* Appearance: Onion skin can make the soup look murky and unattractive.

Instead, you can use the whole onion, including the skin, for flavoring the broth. You can:

* Roast the onion: Roasting brings out the sweetness and depth of flavor.

* Simmer the onion: Simmering the onion in the broth will infuse it with flavor.

Once you've extracted the flavor, you can remove the onion before adding other ingredients and proceed with making your soup.
