buttermilk recipe



  1. Measure the vinegar or lemon juice into a liquid measuring cup.
  2. Fill the measuring cup to the 1-cup mark with milk. Stir and let the mixture rest for at least 5 to 10 minutes. You will see some light separation in the milk (curdling). Use as instructed.


*Vinegar options: Choose from a clear or almost clear vinegar, such as plain distilled vinegar, apple cider vinegar, rice vinegar or Champagne vinegar. They are all similar enough in acidity levels to work well, and I can’t discern a difference in the final flavor of the baked good depending on which is used.

**Milk options: Choose from cow’s milk, nut milk coconut milk, soy milk, oat milk—any milk will do, really!

Make it dairy free/vegan: Choose your favorite dairy free/vegan milk.

Make it nut free: Be sure to use a milk that is nut free.

Make it soy free: Be sure to use a milk that is soy free.
