What Is a Good Replacement for Buttermilk?
A good buttermilk replacement is anything that mimics its acidic and thickened texture, most commonly achieved by combining an acid like lemon juice or vinegar with milk, or using yogurt or sour cream thinned with milk. These substitutes successfully add the necessary tang and moisture to recipes that call for buttermilk.
The Magic of Buttermilk: Beyond the Carton
Buttermilk, despite its misleading name, isn’t usually churned from butter these days. Traditionally, it was the liquid left over after churning butter, naturally acidic and slightly thicker than regular milk. Modern buttermilk is usually cultured, meaning specific bacteria are added to regular milk to create a similar tangy flavor and slightly viscous texture. This process contributes significantly to the moistness and tenderness of baked goods.
Why You Might Need a Buttermilk Substitute
While buttermilk can add incredible depth and texture to recipes, it isn’t always a staple in every refrigerator. You might need a substitute if:
- You’re running low on buttermilk.
- You don’t use buttermilk often and don’t want to buy a whole carton that will expire.
- You have dietary restrictions, like a dairy intolerance (although many substitutes are dairy-based).
- You simply can’t find buttermilk at your local grocery store.
The Top Buttermilk Alternatives: Recipes and Ratios
Several excellent substitutes mimic buttermilk’s properties. Here’s a breakdown of some of the most popular options:
Milk and Lemon Juice or Vinegar: This is the most common and widely recommended substitute.
- Process: Add 1 tablespoon of lemon juice or white vinegar to a liquid measuring cup. Fill the cup with enough milk (dairy or non-dairy) to reach the 1-cup mark. Stir and let it sit for 5-10 minutes until it curdles slightly.
- Ratio: 1 cup buttermilk = 1 tablespoon lemon juice/vinegar + enough milk to reach 1 cup.
Yogurt (Plain, Unsweetened) and Milk: Yogurt provides the acidity and thickness similar to buttermilk.
- Process: Whisk together plain, unsweetened yogurt with milk until it reaches a pourable consistency.
- Ratio: 1 cup buttermilk = 1/2 cup yogurt + 1/2 cup milk.
Sour Cream and Milk: Similar to yogurt, sour cream brings both acidity and richness.
- Process: Whisk together sour cream with milk until smooth and pourable.
- Ratio: 1 cup buttermilk = 1/2 cup sour cream + 1/2 cup milk.
Kefir: Kefir is a fermented milk drink that closely resembles buttermilk in taste and texture. It can be used directly as a 1:1 substitute.
- Ratio: 1 cup buttermilk = 1 cup kefir.
Cream of Tartar and Milk: While less acidic than lemon juice or vinegar, cream of tartar can still contribute to the desired effect when combined with milk.
- Process: Combine cream of tartar with milk.
- Ratio: 1 cup buttermilk = 1 3/4 teaspoon cream of tartar + 1 cup milk.
The Science Behind the Substitute: Why It Works
The key to a successful buttermilk substitute lies in recreating its two primary characteristics: acidity and thickened consistency. The acid helps to tenderize gluten in baked goods, resulting in a softer, more tender crumb. The thickened texture adds moisture and richness. Acids like lemon juice and vinegar curdle the milk slightly, mimicking the texture of buttermilk. Yogurt and sour cream already have a thicker consistency, requiring only thinning with milk.
Potential Pitfalls and Common Mistakes
Using a buttermilk substitute is generally straightforward, but avoiding these common mistakes ensures optimal results:
- Not Letting the Milk Curdle: When using lemon juice or vinegar, allow the mixture to sit for the specified time to allow the milk to curdle properly.
- Using Sweetened Yogurt: Always use plain, unsweetened yogurt for accurate flavor. Sweetened yogurt will add unnecessary sugar and alter the recipe’s overall taste.
- Over-Thinning Yogurt or Sour Cream: Avoid adding too much milk, which can result in a watery batter.
- Using Flavored Milk: Always use plain, unflavored milk as the base for your substitute.
When Buttermilk Is Truly Essential
While substitutes often work well, there are instances where authentic buttermilk might be preferable, especially when:
- The recipe relies heavily on the specific tangy flavor of buttermilk.
- The recipe requires the unique protein structure of real buttermilk for optimal results.
In these cases, seeking out real buttermilk is worth the effort.

Frequently Asked Questions (FAQs)
H4: Can I use non-dairy milk for buttermilk substitutes?
Yes, absolutely! Non-dairy milk like almond milk, soy milk, oat milk, or coconut milk works perfectly in buttermilk substitutes. Just use the same ratios as with dairy milk. Keep in mind that different non-dairy milks will have slightly different flavors, so the final result may vary slightly.
H4: Does the type of vinegar matter?
White vinegar is the most commonly recommended type for buttermilk substitutes because it has a neutral flavor that won’t significantly alter the taste of your recipe. However, apple cider vinegar can also be used, but be aware that it will impart a slightly fruity flavor. Avoid using balsamic vinegar or other strong-flavored vinegars.
H4: Can I use flavored yogurt?
No, flavored yogurt should not be used as a buttermilk substitute. The added sugars and flavorings will significantly alter the taste of your recipe, leading to undesirable results. Always opt for plain, unsweetened yogurt.
H4: What if I don’t have lemon juice or vinegar?
While lemon juice or vinegar are the most common acids, you can experiment with other options like orange juice or even a tiny amount of citric acid. However, be mindful of the potential flavor impact on your recipe.
H4: Can I use the same substitute for both baking and savory applications?
Yes, most buttermilk substitutes are versatile enough for both baking and savory recipes. However, consider the flavor profile of your dish. For instance, kefir or yogurt might be particularly well-suited for savory dishes, while lemon juice and milk work well in both.
H4: What’s the best way to store leftover buttermilk substitute?
If you have leftover buttermilk substitute made with milk, lemon juice, or vinegar, store it in an airtight container in the refrigerator and use it within 1-2 days. Substitutes made with yogurt or sour cream should be stored similarly and used within 3-4 days.
H4: Can I freeze buttermilk substitutes?
Freezing buttermilk substitutes is generally not recommended, especially those made with dairy milk, yogurt, or sour cream. Freezing can alter the texture and consistency, making them less suitable for baking or cooking.
H4: Why does the milk curdle when I add lemon juice or vinegar?
The curdling is a result of the acid reacting with the proteins in the milk. This process denatures the proteins, causing them to clump together and thicken the milk, mimicking the texture of buttermilk.
H4: What if my substitute doesn’t curdle?
If your milk doesn’t curdle after adding lemon juice or vinegar, it could be due to several factors, such as using ultra-pasteurized milk, which has altered proteins, or not allowing enough time for the reaction to occur. Try using a different type of milk or letting it sit for a longer period.
H4: Can I use buttermilk powder as a substitute for liquid buttermilk?
Yes, buttermilk powder can be reconstituted to create liquid buttermilk. Follow the instructions on the package for the correct ratio of powder to water. It’s a convenient option when you don’t want to buy a whole carton of liquid buttermilk. It often has a longer shelf life.
H4: How does buttermilk affect baked goods?
Buttermilk contributes to several desirable qualities in baked goods. The acid tenderizes gluten, resulting in a softer, more tender crumb. It also reacts with baking soda, providing leavening and adding a slight tang to the flavor.
H4: What is the difference between buttermilk and cultured milk?
While often used interchangeably, there’s a slight difference. Buttermilk refers to both the traditional byproduct and the cultured product, while cultured milk is a broader term encompassing any milk fermented with bacteria. Modern buttermilk is typically a type of cultured milk.
