  • 2 tablespoons freshly squeezed lemon juice or white vinegar
  • 1 Cup (8oz / 224g) milk (full or low fat)
  1. Measure the milk into a jug
  2. Stir in lemon juice or vinegar into the milk. Stir to combine. Let sit for 30 minutes at room temperature until the milk begins to curdle and becomes acidic.
  3. Use in place of buttermilk in the recipe as it calls for. And if you don’t use it straight away store it in the fridge for up to 3 days.

Recipe Notes

I don't recommend freezing Buttermilk. Dairy doesn't always defrost the same way.
