Are default food weights for cooked or uncooked food?

The way you can ensure that the right type of staple food is being logged is to preface your food with words "cooked" and "uncooked." For example, searching for "cooked rice" will give you a cooked entry, while searching "uncooked rice" will yield an uncooked entry.

By default, cooked entries will be used, so searching "rice" will give you a cooked entry.
