I keep my table butter in a wide mouth 1/2 pint mason jar, on the counter. The lid keeps the dust and bugs out, it is soft and spreadable and lasts forever. I live alone, and a stick or two lasts for a couple of weeks or longer. The only time I have had a problem was when crumbs got in the butter--they molded.
My stockpile butter lives in the freezer.
I just haven't been the same
since that house fell on my sister.
