My stove was set to “medium” last night, but medium on my large burners is nothing like medium on my small burners. If I had a fancy stove, they would be different again.

Wouldn’t it be nice if the numbers shifted, so that the big burner started at 2 or 3 and went up to 11 or 12?

“This burner goes to 11” jokes aside, ratings based on a constant scale across different stoves could make recipes more universal.
