Pioneer cooks relied on fresh buttermilk for extra light biscuits. Try substituting plain yogurt or Saco buttermilk powder. If using for shortcake, reduce salt to 1/4 tsp. and increase sugar to 2 tablespoons. But made as is, with fresh buttermilk, butter, and a gentle hand, these are high rising, tender biscuits, that are perfect with the Thanksgiving main meal or wonderful, the morning after, warmed and slathered with butter and strawberry preserves.
