In all of our recipes where butter is an ingredient, we list the butter as unsalted butter. This is because the amount of salt in salted butter can vary. Many manufacturers of salted butter will have salt listed as 0.9 grams/Tablespoon, which correlates to 7.2 grams/1 stick (8 Tablespoons) of butter.
Unsalted butter usually has a fresher taste as well.
Here are two examples of how much extra salt will be added to a recipe if you choose salted butter instead of unsalted butter.
The Sour Cream Butter Cake’s ingredients in The Cake Bible includes:
Unsalted butter: 170 grams / 12 Tablespoons
Salt: 3 grams / 1/2 teaspoon
If you used salted butter and no additional salt instead, the salt in the butter translates to: 0.9 grams/Tablespoon x 12 tablespoons of butter:
Butter’s Salt: 10.8 grams / 1-1/2 +1/16 teaspoons
Over 3 times the amount of salt for the recipe using UNsalted butter
Looking at a popular recipe like Chocolate Chip cookies using salted butter, whether with or without including the salt listed on the ingredients, will almost always increase the amount of salt for the recipe.
A popular internet recipe includes:
Unsalted butter: 113 grams / 8Tablespoon
Salt: 6 grams / 1 teaspoon
If you used salted butter and no additional salt instead, the salt in the butter translates to: 0.9 grams/Tablespoon x 8 tablespoons of butter:
Butter’s Salt: 7.2 grams / 1-1/4 teaspoons
If we were to include the specified salt: 6 grams/ 1 teaspoon
More than 2 times the amount of salt for the recipe using UNsalted butter
Unsalted butter is the answer for your baking.
