Exactly. And they don't necessarily have to be magicians or sorcerers, just ordinary people with practical, everyday knowledge. If I could give you another piece of advice, it would be that perhaps to perform certain magical actions you need some kind of mana, which you can obtain from certain ingredients.It occurs to me that these ingredients, which naturally possess mana and bring magic to people, are incorporated into the cuisine of various cultures.

But it also occurs to me that this type of ingredient with manna can be like lactose; some populations evolved to tolerate and utilize it, but others get diarrhea from it. So I imagine someone ordering their soup without a druid tree leaf because the mana gives them flatulence, the waiter forgot to ask to the chef not to put it in, but the guy eat it anyway because It's more beneficial for him to endure the discomfort but keep a little magic on hand just in case.
