What is buttermilk?

Traditionally, buttermilk refers to sour liquid leftover after churning homemade butter. Naturally, and contrary to the name, it's non-fatty and gives off a sour and tangy flavour. It's great for cakey goods because it results in a tender crumb and ultimately moist bakes. Also, due to its acidity, it helps break down proteins such as gluten, providing a delicate texture.

Recipe

  • 250ml whole or semi-skimmed milk
  • 1 tbsp lemon juice or vinegar

Any type of vinegar will work, as long as it's relatively neutral in flavour. You can also use any kind of milk that you prefer for this recipe, including whole, semi, and even almond milk.

FAQ

Can you freeze buttermilk?

Can you use dairy-free products?

It's recommended to use homemade buttermilk within 3-4 days of making it, when stored in the fridge. If frozen, use within 3 months.

What can I use buttermilk for?

Buttermilk is great for so many baked goods. Use in recipes for cakes, cupcakes, biscuits, scones, brownies, cookies, and even non-baked goodies such as pancakes.

What can I use as a substitute for buttermilk?

There are many things you can use in the event that you don't have any buttermilk to hand. Sour cream is a great option, when thinned out a little using water or milk. Plain yoghurt thinned out with water/milk, or unflavoured Kefir, are some another alternatives.

For a vegan friendly option, try unsweetened soy milk with either lemon juice or vinegar.
