Ingredients

  • 1 TB vinegar
  • 1 cup non-dairy milk of choice

Instructions

  • Take a liquid measuring cup and place 1 TB of the vinegar into the cup, fill it up the rest of the way with the non-dairy milk to the 1 cup line and stir to combine.
  • Let this sit for 5 minutes and thicken. Once it's thickened, use it as needed in your recipe.

Notes

Storing- This will keep in an airtight container for up to 4 days.
Freezing- I would make it fresh because it only takes a few minutes. However, if you prefer to freeze things, it's best to freeze them in an ice cube tray and then place the frozen cubes in a freezer-safe bag. Defrost in a measuring cup on the counter until defrosted, and then use accordingly.
Expert Tips and Tricks- 
  • Nondairy milk that will produce a thicker buttermilk substitute are fuller-fat oat milk, unsweetened soy milk, Coconut milk (this will leave a coconut flavor in your buttermilk and won't curdle as well), Fuller-fat cashew milk, and any of the new vegan whole milk that they have come out with.
  • Nondairy milk that will produce a thinner buttermilk substitute is Almond milk, low-fat oat milk, low-fat cashew milk, and rice milk.
  • I have used all of these, but the thicker milk gives you the right consistency of buttermilk, which is a thicker consistency.  But it will work with the thinner milk; I've done it many times before it will have a thinner consistency. Some non-dairy milk brands curdle the milk better than others. What you're looking for when it's made is a thick, almost separated milk.
