If you have a recipe for saleted butter, but only have unsalted, surely you can use the unsalted with a little bit of extra salt in the recipe, right? How much salt would you add per 1/2 cup (stick) of butter?
It depends on what you are making, how much salt to add. If there is no other salt in the recipe, betwee, 1/4 and 1 whole teaspoon of salt. I would err on the short side, rather than over salt it.
Thank you so much!
