Ever wanted to know how to make homemade buttermilk at home? This 2-ingredient recipe is quick, easy, and works every single time! Buttermilk makes fluffier pancakes and waffles, and it gives baked goods an extremely moist texture.

Ingredients

Scale
  • 1 cup (240 ml) milk*
  • 1 Tablespoon fresh lemon juice** (or white vinegar)

Instructions

  1. Add one Tablespoon of fresh lemon juice (or white vinegar) to a measuring cup or pitcher.
  2. Pour the milk over, until you reach the 1-cup (240 ml) level.
  3. Gently stir and let the mixture sit for about 5-10 minutes. This will allow the milk to slightly curdle, giving it a buttermilk-like texture and taste. Stir again and use as needed.

Notes

* You can use whole milk, 2% or skim milk. For a dairy-free version, replace with full-fat coconut milk.

** I recommend you use freshly squeezed lemon juice from whole lemons.
