Use Unsalted Butter

I like the taste of salted butter, but it recently occurred to me that a lot of the things that I have with it - peanut butter, cheese, yeast extract - contain a fair amount of salt themselves. So I experimented with spreading bread or toast with unsalted butter when using these fillings, and found that I didn't miss the salt. In fact, unsalted butter tastes better with peanut butter than salted - its slight sweetness is a good complement.
