Which spice is described by the phrase: "You can't eat it raw, but once boiled, you throw it out"?

Thanks for the explanation. I have used them all my grown up life but never knew where they originated. They are always in my cupboard.

Love them ,cannot cook any stew without bay leaves. Or tea.

bay leaf is a herb not a spice

Julius Caesar laurel wreath that represents honor and glory was made of bay leafs and also made his bald spot look more glorious

Kompis, dangerous to eat

Kompis, you must discard them. Dangerous

What about the boiling part?
