What is Buttermilk?

It is called buttermilk simply because it is a valuable liquid product you can attain after the process of making butter. But to this date, there are now two ways to make it. One of them is via the traditional churning and the other is adding cultures to regular milk.

In terms of acidity, buttermilk is naturally acidic, unlike regular milk. It also has lower calories and fat content than milk. It is also higher in calcium and rich in potassium and Vitamin B12.

There are a plethora of ways you can use buttermilk, from tenderizing meat to make your baked goods rise. It also gives your dishes a slight tanginess, utterly improving the recipes that call for it. From fried chicken to biscuits, it just knows its way to bring better results to your cooking.

Types of Buttermilk 

If you’ve ever wondered about how to make real buttermilk, let’s talk about its two main types and how they differ from each other. 

The original version is called the churned buttermilk. It is the leftover liquid after churning butter from fermented cream. This type of buttermilk is the traditional way to make it.

On the other hand, cultured buttermilk is the modern type of it that we use today. It is made from mixing dairy cultures with regular milk. This is now widely commercialized, especially in the U.S.

What Does Buttermilk Taste Like?

Given its acidity, it gives off a sour and tangy taste with distinctive hints of creamy, buttery taste and aroma. Unlike regular milk with natural creaminess and sweetness. It is safe to drink buttermilk straight away, although it’s commonly used for cooking and baking.

Substitutes For Baking

If used in baking, buttermilk helps with keeping your baked goods moist and tender, especially for making fluffy buttermilk pancakes, muffins, and waffles. This also helps buttermilk biscuits become lighter and have a fuller consistency because it reacts well with baking leaveners, helping your pastries rise. We suggest enjoying your homemade pastries with a comforting cup of hot Jasmine tea

Buttermilk also gives your dishes additional creaminess and slight tanginess when incorporated in dishes.

In cooking, it’s all about the additional flavor that it gives.

Good news to those who are lactose intolerant, there’s also a buttermilk substitute that’s perfect for you. Here’s how to make a vegan buttermilk substitute with the use of soy milk, almond milk, and coconut milk.

Soy Milk and Lemon Juice

1 tablespoon lemon juice


  1. Pour the soy milk into a container and add the freshly squeezed lemon juice.
  2. Let it sit for 2 to 5 minutes to let it curdle.
  3. Enjoy your vegan homemade substitute!

Instead of using soy milk, another non-dairy milk ingredient you can use is almond milk. Make your buttermilk substitute using almond milk by following the instructions below:

Almond Milk and Lemon Juice


1 scant cup of almond milk

1 tablespoon lemon juice


  1. Take the almond milk and mix the lemon juice along.
  2. Stir it up and let it sit for at least 3 minutes to thicken.

If you don’t have freshly squeezed lemon juice, you can use vinegar instead in a 1:1 ratio. This is guaranteed to work with both soy and almond milk. Also, remember that not all dairy free milk will curdle when you use lemon juice. Coconut milk, for example, will not react to the acidity of lemon.

Buttermilk Vs. Regular Milk

difference between buttermilk and regular milk

Milk and buttermilk may look alike but they’re completely different from each other. If your recipe calls for buttermilk, you cannot just use milk in its place. There’s always a reason why a recipe calls for buttermilk instead of milk. Their differences include:


If you look at both from afar, you will not notice any difference at first. They’re both white, but one will seem to have a thicker consistency. Buttermilk is denser than regular milk or cow’s milk. Cultured buttermilk’s fermentation process is what makes it thick and curd-like. On the other hand, regular milk has a distinct thin consistency.


The usual milk that is served on our tables is made of processing milk from cows or other mammals such as goats. Milk can also come in the forms of powdered, condensed, and evaporated. While on the other hand, buttermilk can only be attained by the churning of butter or mixing cultures with fermented milk.

How To Store Buttermilk

If you’re planning to make a whole batch of homemade buttermilk, you must know how to properly store it or your efforts will all go to waste.

After successfully making your homemade substitutes, take a clear container. It must be a transparent container, so you will be able to see the state of your product. Cover your container tightly and refrigerate. Always make sure to put it back in the fridge immediately after use.

How Long Does Buttermilk Last?

If unopened and frozen, buttermilk can last longer than the indicated expiration date. But initially, (opened or not) it can only last up to 14 days. We should keep it chilled and refrigerated at all times to avoid immediate spoilage. However, if you notice changes in your buttermilk’s appearance and smell, it’s wiser to get rid of it to avoid getting sick.
