How to Make Buttermilk

Recipe From Dr. Mercola

Bakers use a wide array of ingredients to help them get the right flavor and texture for the baked goods and pastries they make. One of these ingredients is buttermilk, a milk by-product used for making fluffier pancakes, scones and biscuits.1

What Is Buttermilk?

Buttermilk has been around for hundreds of years, with the old-fashioned type being a product of churning butter. In the original process of producing buttermilk, the leftover liquid from churning is left to set for a specific time period to let the cream separate, allowing bacteria to ferment the milk and produce lactic acid.2 Today, the product of this process is what’s called old-fashioned buttermilk, as opposed to cultured and faux buttermilk.

In India, buttermilk is called “takra,” which is a popular drink used as a digestive and disease aid. Through the years, it’s been used for its astringent properties and its effect on swelling, irritation and gastrointestinal conditions.3 It’s also worth noting that buttermilk is rich in a variety of minerals, including calcium, phosphorus, potassium and protein, all of which are essential for body processes.4

Cooks and bakers note that buttermilk may be used to make better pastries and baked goods. It’s well-known for improving the rise and crumbliness of these foods.5 However, because some people would rather use shortcuts, faux buttermilk became a thing, which refers to mixing milk with an acidic substance to achieve its distinct tanginess.6 While the flavor might be similar in a way, faux buttermilk might lack some of the components of cultured buttermilk because it is not fermented.

Here’s How You Can Make Buttermilk at Home

While cultured buttermilk can usually be found in your local grocery stores and farmers markets, you can make your own. Not only will you learn something new, but you’ll also be able to control the quality of all the ingredients you’re going to be using. But how exactly do you make buttermilk? Here’s a guide from The Prairie Homestead to help you out:7

Homemade Buttermilk


  • 4 cups raw grass fed milk
  • 1 packet buttermilk starter culture or 1/8 teaspoon mesophilic starter culture


  1. In a Mason jar, gently stir the starter culture into the milk. Cover the jar with a clean towel and a rubber band.
  2. Avoid capping it tightly with a lid, as the culture needs room to breathe.
  3. Allow the milk to culture at room temperature for 12 to 24 hours. You’ll know the buttermilk is ready when it develops a tangy smell and a thick consistency.
  4. Store your buttermilk in the refrigerator or use accordingly.

Improve Your Pastries With Buttermilk

If you’ve had buttermilk pancakes, you’re familiar with the difference in fluffiness compared to your normal batch. But aside from the distinct texture and taste it lends traditional recipes, buttermilk also provides numerous nutritional components that can benefit you. However, note that not all buttermilks available in the market are made with the same quality. When choosing, make sure that you look for the organic and grass fed type. Better yet, go for the buttermilk available in farmers markets so you’re assured of the quality.
