How many times have you pulled out a recipe for cake, gone through the list of ingredients and realized that you don’t have that one elusive ingredient that so many recipes use – buttermilk? It is one of the simplest ingredients and a by product when you churn butter out of cream. But who really does that anymore at home? Which basically means that I’m always stumped when a recipe calls for buttermilk.
The next time you need some when baking, don’t be disappointed. You can make buttermilk at home in under 10 minutes, is far easier than you think and requires only two ingredients!
The Two Ingredients
This quick buttermilk recipe uses only two ingredients – milk and an acid which will help curdle the milk quickly and turn it into buttermilk. There are three different acids you can use: vinegar, lemon juice or plain yogurt. The process is really simple – mix the acid in the milk and then let it sit for 10 minutes till you see the milk curdling, and curds forming. And there, it’s ready!

Step 02: Add an acidic agent of your choice. I have used vinegar, but you can use lime juice or even plain yogurt.

Step 03: Mix everything well, and allow this milk and acid mixture to sit for about 10 minutes.

Step 04: After 10 minutes you’ll notice that the milk has curdled and your homemade buttermilk is ready!
Frequently Asked Questions
The science behind using Buttermilk for Baking
A lot of baking recipes call for baking soda that is neutral. Buttermilk on the other hand is highly acidic due to the presence of lactic and citric acid and the lactobacillus present in it. The bacteria reacts with the neutral soda to produce carbon dioxide which helps fluff up cakes and pancakes beautifully. The reaction is almost instant, which is why it is recommended to mix both ingredients and hence requires for the mixing of both ingredients to be done only when other preparations and preheating has been arranged for. Buttermilk adds a lot of texture and tanginess to dishes and is way better than milk which is otherwise basic.
This homemade buttermilk recipe is a great substitute when you don’t have some available at home. It’s even faster than heading out to the store to buy some.
Different Ways to Use Buttermilk

Common questions
1. Why do bakers use buttermilk?
Buttermilk helps activate the baking soda, which allows the cake to rise when baked and become fluffy. Secondly, buttermilk adds a slight tanginess, which balances out the sweetness in baked goods.
2. What if I don’t have milk?
Another substitute for homemade buttermilk if you don’t have milk at home is to dilute plain yogurt. Dilute it in 1:1 ratio which is 1 part yogurt with 1 part water and you can use this mixture in place of buttermilk.
3. Can I make this dairy free?
Even though I haven’t tried this, I think it should work. To make a dairy-free buttermilk, simply mix your favourite vegan milk and an acid of your choice. Mix, allow it to rest and your vegan buttermilk should be ready to be used!
4. How to store leftovers?
Any leftover buttermilk can easily be stored in the refrigerator for up to 2 weeks if stored in a clean airtight container. You can even freeze buttermilk in freezer-safe bags or ice cube trays for up to 3 months! Simply thaw the desired amount in the fridge overnight and add it to your favorite recipes. So simple and convenient!
