Use Unsalted Butter Instead Of Salted Butter. So if you use butter sparingly salted may be the best choice. However sometimes a recipe calls for salted butter but all you have is unsalted butter.
Keep in mind the shelf life of salted butter can also be a downside since the salt can actually mask smellsflavors of rancidity. When you want to control the saltiness of your dessert use Unsalted Butter and add the appropriate amount of salt to the recipe yourself. You can definitely use salted butter and unsalted interchangeably.
It simply has a longer shelf life.
So heres a simple rule of thumb to use so you can make the recipe with unsalted butter. In general due to the lack of control of added salt most of the time unsalted butter is the go-to choice in baking. Similarly half tsp salt for 2 sticks one tsp salt for 4 sticks and so on ie 4 US sticks of butter 1 teaspoon of salt. Thats the only tweak you need to make.
