DIY: Homemade Buttermilk

Buttermilk is one of those pesky ingredients that I never seem to have when I need it. It pains me to buy a carton of it when I know I only need a cup of the stuff too. Grrr! Well I think I finally solved my own problem: homemade buttermilk!

The ingredients are simple: milk (any kind but I’d recommend 2%) and a fresh lemon. Whatever you do, don’t use bottled lemon juice!


Squeeze the juice from half of a lemon into a 1-cup measuring cup. It should yield 1-2 teaspoons. Then pour the milk into the same measuring cup until you’ve reached the 1-cup line.


Give it a quick stir and walk away for 15 minutes. Don’t touch it. Don’t worry about it. Just walk away.


After 15 minutes, the milk will have curdled. This is exactly what you want! The consistency will be slightly chunky and the scent will have shifted from the sweet-ish smell of milk to the tangy and also sour smell of buttermilk.


That’s it! Use this homemade buttermilk in any recipe that calls for buttermilk. Here are a few suggestions: Buttermilk Corn Muffins, Spicy Chicken Drumettes, or Cheddar, Chive, and Bacon Biscuits.

If you need more than one cup just repeat the process for each cup of buttermilk needed.

  1. Omg! This is so useful. I live in the UK and can never ever find buttermilk in the shops when I need it. Thanks for publishing this.
