There are times when you're craving pancakes made with buttermilk, but there's none in the fridge. So, what do you do if you only need one cup of buttermilk and don't want to buy a whole liter? The good news is that you can easily make buttermilk from regular milk and an acidic ingredient like lemon juice or white vinegar. Let's get started!
Ingredients
- 1 cup (240ml) whole milk or 2% milk
- 1 tablespoon (15ml) lemon juice or white vinegar
- 1.75 teaspoons cream of tartar (optional)
- 0.75 cup (180ml) yogurt, sour cream, or kefir (optional)
Steps
Add an acidic ingredient to regular milk

Pour 1 tablespoon of an acidic liquid into 1 cup of milk. White vinegar and lemon juice are two common acidic liquids that work well for this purpose. Pour the milk into a measuring cup, then add lemon juice or vinegar into the milk.
- You can use whole milk or 2% milk. Skim milk has too little fat to properly thicken.
- Many prefer using lemon juice for curdling the milk, but white vinegar works just as effectively. Lemon juice combines gently with the milk's fat, enhancing the flavor.
- If you need to make more, simply double the acidic ingredient. For example, add 2 tablespoons of the acidic liquid to 2 cups of milk to make 2 cups of buttermilk.
Stir the mixture and let it sit for 5-10 minutes. Just give it a quick stir with a spoon. After 5-10 minutes, the milk will start to curdle. Small clumps will begin to form from the lemon juice or vinegar.
- The mixture will thicken, though not exactly like traditional buttermilk, but it will still work well in recipes.
Stir 1.75 teaspoons of cream of tartar into 1 cup (240ml) of milk. Similar to lemon juice or vinegar, let the mixture sit for 5-10 minutes. The mixture will begin to thicken and curdle during this time.

Use your homemade buttermilk just like you would use the store-bought kind. Simply add the mixture and the thickened part as required in your recipe. No one will notice the difference between homemade and regular buttermilk. Try using it in these recipes:
- Pancakes
- Biscuits
- Fried chicken
- Salad dressing
- Scones

Learn how to make traditional buttermilk if you're interested in the process. Traditional buttermilk is a byproduct of making butter from cream. A probiotic culture is added to the cream to separate the fat from the remaining liquid, which is the traditional buttermilk.
- By learning how to make traditional buttermilk, you'll also discover how to make pure butter!
Substitute with yogurt or sour cream
Mix 0.75 cup (180ml) of plain yogurt with 0.25 cup (60ml) of water. Stir the ingredients well to create a thick, flavorful liquid with the texture and taste of buttermilk.
- You can use whole milk or 2% milk instead of water for a thicker consistency, especially when using low-fat yogurt.
- If using thick yogurt like Greek yogurt, you'll need to add a bit more liquid to achieve the desired texture.
Try combining sour cream and water in a 3:1 ratio. If you don't have plain yogurt on hand, mix 0.75 cup of sour cream with 0.25 cup of water. Stir until the mixture reaches the consistency of buttermilk.
- Just like with yogurt, you can substitute milk for water to create a thicker mixture, especially when using low-fat sour cream.
Mix kefir grains with water in a 3:1 ratio. Kefir grains work just as well as yogurt or sour cream. However, the result may vary slightly, so you'll need around 0.25 cup (60ml) of water to 0.75 cup (180ml) of kefir grains to create a buttermilk-like texture. Start by adding a small amount of water, stir, and then add more if needed to thin the mixture.
- As with the other options, you can use milk instead of water if desired.

Try incorporating low-fat yogurt, sour cream, or kefir grains into your recipes. While these substitutes may not provide the authentic taste or mix as seamlessly as traditional buttermilk, they offer a quick solution and still work well in your recipes. Experiment and compare the results with using vinegar or lemon juice and milk.
- Try the flavor by making 3 batches of pancakes using buttermilk – one with traditional buttermilk, one with vinegar/lemon juice/cream of tartar and milk, and the other with sour cream/yogurt/kefir grains and water. Then, invite a few friends to taste-test your pancakes!
Tips
- Store-bought buttermilk is often just skim milk with probiotics or sour fermented milk. If you've never tried traditional buttermilk, you should give it a try! Many people believe it tastes better than the store-bought version.
