Ingredients
- Buy heavy cream. Put it in a jar and shake for a very very long
- time. It will eventually become butter. (Alternately, you can
- use a food processor to speed up the process.) After you have
- little lumps and flakes of butter, you must "wash" it. Drain the
- liquid (save it for making cream based soups!) And mold the butter
- into a lump. Under cold running water, knead it gently for 5
- minutes (I fold, press flat, fold, press flat, etc). Add salt, if
- desired (I don't), knead it in to distribute it evenly. Mold, then
- refrigerate.
