If you've ever bought terra cotta pots and they seemed too pristine,
there is a simple process for "aging" them and achieving that sweet patina many of us insist upon.
I've heard of several "recipes" for mellowing the clay, but this one is simple.
Take a piece of sandpaper and lightly scuff the pot - not all over, but here and there.
Soak it in water for a few minutes. (While you scuff the next ones.)
Place them in a container and pour buttermilk or yogurt over them.
Make sure you smear them up well.
Cover the whole smelly mess and place it outside for a few days.
The pots will soak up the acidophilus and it will grow in the nice moist clay.
Voila: aged pots!
