What is Buttermilk?

Buttermilk is a fermented dairy product that has been used in cooking and baking for centuries. Traditionally, buttermilk was the liquid left behind after churning butter from cream. Today, buttermilk is commonly made by adding lactic acid bacteria to milk, which causes it to ferment and develop its characteristic tangy flavor.

Buttermilk is a versatile ingredient that adds a unique flavor and texture to recipes. Its acidity can also help tenderize meats and add moisture to baked goods. Though it’s commonly used in Southern cuisine, buttermilk is a popular ingredient worldwide, from Indian lassi to Russian kefir.

Fun fact: In some cultures, buttermilk is also believed to have health benefits, such as aiding digestion and boosting the immune system.

How to Make Buttermilk from Milk

Buttermilk is a versatile ingredient that can add tanginess and richness to various dishes, from pancakes and biscuits to dressings and marinades. Making buttermilk from milk is surprisingly easy, and you only need two key ingredients and some basic equipment.


  • 1 cup of milk
  • 1 tablespoon of white vinegar or lemon juice


  1. Pour the milk into a measuring cup or bowl.
  2. Add the white vinegar or lemon juice and stir thoroughly.
  3. Let the mixture sit at room temperature for 5 to 10 minutes. The acid will cause the milk to thicken and curdle, resembling buttermilk.
  4. Use the buttermilk immediately or cover it and refrigerate until ready to use. It will keep for up to one week in the fridge.

That’s it! You have created your own buttermilk from milk in just a few simple steps. The acidity of the vinegar or lemon juice helps to mimic the tanginess of traditional buttermilk, while the milk provides the consistency and creaminess.

You can also adjust the thickness and tanginess of the buttermilk by using more or less vinegar or lemon juice, or by swapping it with other acids like yogurt or cream of tartar.

Tips and Variations for Homemade Buttermilk

Congratulations on making your own homemade buttermilk from milk! Now that you have a batch of tangy, creamy goodness, it’s time to take it to the next level with some expert tips and variations. Here are some ways to customize your buttermilk based on your preferences and recipe requirements:

How To Make Buttermilk

Adjust the Thickness

If you prefer a thicker buttermilk consistency, simply add more milk to the recipe. This will decrease the tanginess slightly, but you can always adjust with some extra lemon juice or vinegar. Alternatively, if you need a thinner consistency, try reducing the amount of milk or increasing the acid content.

Enhance the Tanginess

If you enjoy a more tangy flavor, increase the acid in your recipe by adding extra lemon juice or vinegar. You can also let your buttermilk sit at room temperature for a longer period to allow the good bacteria to develop even more. Keep in mind that a more tangy buttermilk may not work for all recipes, so adjust accordingly.

Infuse with Herbs and Spices

Add some extra flavor to your buttermilk by infusing it with your favorite herbs and spices. This is a great way to customize your buttermilk for specific recipes, such as using dill for a savory dip or cinnamon for a sweet dessert sauce. Simply mix in the desired herbs or spices, let sit for a few hours or overnight, and strain before use.

Substitute with Alternative Milk

While traditional buttermilk is made from cow’s milk, you can also make a similar version with alternative milk such as almond, soy, or coconut milk. Simply use the same process as you would with regular milk and the acid of choice. Keep in mind that the flavor may be slightly different, but still delicious and versatile.

With these handy tips and variations, you can elevate your homemade buttermilk game and take your culinary creations to new heights. Experiment, have fun, and enjoy the flexibility and freshness of making your own buttermilk from milk.
