Discriminating bakers and chefs typically use unsalted butter in their recipes because it gives them more control over the salt content and flavor of their dishes. However, sometimes a recipe calls for salted butter, but all you have is unsalted butter. So here’s a simple rule of thumb to use so you can make the recipe with unsalted butter. Just remember, for every half cup (1 stick or ¼ lb) of salted butter required, you can add ¼ teaspoon of salt to Challenge Unsalted Butter.

1. 1

2. 2
   But if you only have unsalted butter when the recipe calls for regular butter, you can add a ¼ teaspoon of salt for every stick or ½ cup of Challenge Unsalted Butter required.
