Recipe tips and variations

  • Yield: This recipe makes about 1 cup of buttermilk.
  • Storage: Store covered in the refrigerator for up to 2 weeks. Stir or shake to recombine before using.
  • Make buttermilk with yogurt: Combine ¾ cup plain yogurt with ¼ cup milk.
  • Make buttermilk with cream of tartar: Stir together 1 cup of whole or 2% milk and 1 ¾ teaspoon cream of tartar. First, mix the cream of tartar with 2 tablespoons of milk to form a loose paste; this keeps the cream of tartar from forming lumps. Then, add the rest of the milk.
  • Buttermilk batter: Fried chicken, chicken fried steak, and fried green tomatoes are all better with buttermilk.
  • Salad dressing: Ranch dressing and blue cheese dressing get their delicious tang and creaminess from buttermilk.
  • Irish soda bread: The acid in buttermilk mixed with baking soda makes this bread rise.
