I use salted butter for everything that requires butter, provided its available. I always keep at least 2-3 lbs of butter on hand in the freezer. When salted butter isn’t available and I need butter to keep my reserve on hand in the freezer I’ll buy unsalted and use it for baking only and I don’t add extra salt to the recipe to compensate for the unsalted butter. The amount of salt in salted butter is minimal, and is really only a flavor enhancer.
Personally, I think unsalted butter has little flavor. I don’t like overly salty food, but I do think that salt enhances the flavor of butter and the foods it is used on or in. And when I use it in baking and cooking I seldom make any adjustments in the salt I use in the recipe, unless the recipe calls for a lot of salt, then I may reduce the amount by 1/4 to 1/2.
Unsalted butter on toast, english muffins, pancakes, waffles and sandwiches is tasteless, you may as well spread Crisco on these foods for all the flavor it provides.
I say use what you like best. I realize this opinion is contrary to many, but it works for me.
BTW, when I was a teen we bought un homogenized milk from the neighbor and it was my chore to make the butter from the top cream. I used to put 1/2 tsp of salt in each lb. of butter and it wasn’t overly salty tasting, tasted just like the butter we bought from the store. So, using a 1/2 tsp to 1 tsp of butter in vegetables or rice would be adding only a few grains of salt the the finished dish. Its all a matter of taste.
