ToggleWhy You'll Love Cultured Buttermilk

If you have dairy animals on your homestead, then you know the importance of efficiently and safely processing raw milk at home. We focus on making homemade dairy products practical to avoid burning out on keeping up with our milk supply.
This comes in the form of making quick and easy dairy products that also extend the shelf life, like Instant Pot yogurt, wholesome raw milk cottage cheese, homemade marinated yogurt cheese, and easy homemade kefir. But, quite possibly the easiest dairy product we make is cultured buttermilk.
This cultured dairy product proves to be indispensable in our kitchen beyond this easy homemade buttermilk ranch dressing recipe. Here’s why you need to add cultured buttermilk to your kitchen, too.
- Easy to Make - As mentioned above, cultured buttermilk is quite possibly the easiest dairy product we make. I requires just two ingredients and two minutes of hands-on time, it couldn’t be easier!
- Inexpensive - Due to the simple ingredients and minimal equipment, you can save money making your own buttermilk rather than using store-bought buttermilk.
- Preservation - Cultured buttermilk lasts much longer than regular milk, so you can extend the shelf life and get the most out of your milk.
- Improves Health - Culturing buttermilk classifies it as a fermented food, which can improve gut health.
- Improves Recipes - Buttermilk has unique properties that enhance the flavor and texture of many recipes. (Keep reading to learn more about that!)
Cultured Buttermilk vs. Traditional Buttermilk

Buttermilk falls into two main categories: cultured buttermilk and traditional buttermilk. You can use both in many recipes, but they come from different processes. Traditional buttermilk is the liquid left after making this homemade butter recipe, and it has a lighter taste than cultured buttermilk.
However, you can make cultured buttermilk by adding good bacteria to milk, which starts a fermentation process that gives it a unique, tangy and rich flavor profile.
If you don’t have buttermilk handy, you can substitute Instant Pot yogurt, easy homemade kefir, or even a faux buttermilk in a pinch. Mix a tablespoon of lemon juice or white vinegar with 1 cup of milk and let it sit at room temperature for 5 to 10 minutes.
However, if you have time to make cultured buttermilk, it’s worth the effort because with faux buttermilk, you will be missing out on the health benefits of the live cultures.
Ingredients Needed

- Cultured Buttermilk - You need to begin with store-bought buttermilk, but then you can use your homemade buttermilk to make continuous batches.
- Whole Milk - Because we have dairy cows, we use raw milk, but pasteurized milk works, too.
Step-by-Step Instructions

Step 1: Pour milk and buttermilk into a clean quart jar.

Step 2: Stir with a clean spoon.

Step 3: Place the lid on top, but do not seal it. Allow the mixture to culture at room temperature for about 24 hours.

Step 4: Seal the lid and store the buttermilk in the refrigerator for up to two weeks.
Storing Cultured Buttermilk

To store extra or prolong the shelf life, pour the buttermilk into ice cube trays, freeze, and then transfer them to a zip-top bag to store in the freezer for about six months.
Furthermore, you can follow this tutorial for freeze drying milk to freeze dry buttermilk so it's shelf-stable!
Ways to Use Cultured Buttermilk

The lactic acid content in buttermilk is the key component to why buttermilk improves so many recipes.
The reaction of buttermilk’s acid with the leavening agents in baked goods creates carbon dioxide, resulting in a light and fluffy feel. You can swap buttermilk for the milk in any cake, muffin, sweet bread, pancake, or biscuit recipe, such as…
- Country Whole Wheat Biscuits
- Whole Wheat Scones
- Easy Sourdough Pancakes
- Heavenly Gluten-Free Cinnamon Rolls Recipe
- Parker House Rolls Made With Sourdough
- Rhubarb Breakfast Cake
- Quick & Easy Cobbler
- Chocolate Potato Cake
- Gluten-Free Pumpkin Bread
As mentioned in our post on cooking tips for organ meats, soaking the meat in buttermilk can help neutralize unpleasant cooking odors. You can also use buttermilk to neutralize the “gamey” flavor in wild game meat.
Additionally, buttermilk's acid is a great tenderizer, so soaking tough cuts in buttermilk for 6-8 hours before cooking helps.
Finally, the bacteria in cultured buttermilk provide a nutritional boost to recipes that are not cooked. Try buttermilk in your favorite green smoothie recipe, homemade buttermilk ranch dressing recipe, or even swap the milk for buttermilk in this homemade ice cream recipe!
