Does salting your cooking change the effects/regen hearts of a recipe?

Does adding rock salt to a recipe add any hearts or change the effect comparing it to the same recipe but without the rock salt?

Rock Salt increases the duration of whatever effects your meal has. If you are just using food to restore hearts, Rock Salt has no effect.
