"Why do some recipes call for unsalted butter then add salt? Is there a
reason or is this just left over from the time people churned the milk to
get butter?
Herman Reinhart"
First, unsalted butter is ALWAYS fresher than the salted
stuff. Manufactuers often times salt regular butter when it gets close to
spoiling in order to set back the sell by date.
Second, the amount of salt in salted butter is never really known. It
changes from brand to brand, and even if you didn't add salt to the recipe,
it can still really affect the taste. Often the amount of salt in salted
butter is too much for yeast in a bread recipe.
So, for a much fresher, cleaner taste in the product and consistent
results, always use unsalted butter.
