I was a bit nervous about doing this, but seeing how high the cost of buttermilk is these days, I thought I would try this (at least until we get our OWN milk to make butter, and buttermilk).
INGREDIENTS:
one-quart glass jar
2 TBLS. existing buttermilk (storebought or previous homemade batch)
milk (whole preferably)
DIRECTIONS:
In the one-quart jar put two (2) tablespoons of store bought buttermilk, filling the jar the rest of the way with milk (I used whole). Close jar tight and place in dark, cool(er) cupboard for about 20 hours (I let mine sit a little longer and it’s just fine). After the sitting period is ‘up’, you have a full jar of real buttermilk. Place your jar of buttermilk in the fridge and use in all of those recipes calling for buttermilk.
