  • 1 scant cup milk or cream (see notes)
  • 1 tablespoon fresh squeezed lemon juice or white vinegar


  • In a liquid measuring cup or small bowl, stir together the milk and lemon juice (or vinegar).
  • Let the mixture rest for 5-10 minutes, until slightly curdled. It will not be as thick as regular buttermilk.
  • Use buttermilk substitute, including the curdled bits, in your recipe.


Yields 1 cup; recipe can be doubled, tripled, halved (etc) as needed.
This recipe will work with any type of milk, though I recommend using something with at least 2% fat for best results.
Use soy milk in place of the dairy milk for a vegan buttermilk substitute.
