How to Make Buttermilk and what it is?
Buttermilk is a versatile, slightly tangy dairy product commonly used in baking, marinades, and dressings. While traditional buttermilk was a byproduct of churning butter, the modern version is cultured buttermilk made by fermenting milk with lactic acid bacteria.
Traditional Buttermilk vs. Cultured Buttermilk
- Traditional Buttermilk: In the past, buttermilk was the liquid left over after churning butter from cream. It was naturally fermented, making it slightly tangy and rich in probiotics.
- Cultured Buttermilk: Today, most store-bought buttermilk is made by adding lactic acid bacteria to regular milk. This process thickens the milk and gives it a tangy flavor, making it ideal for cooking and baking.
Why Buttermilk is Essential in Baking & Cooking
Buttermilk plays a crucial role in various recipes due to its unique properties:
✔️ Makes baked goods fluffier – The acidity in buttermilk reacts with baking soda, creating carbon dioxide bubbles that result in lighter, airier textures.
✔️ Adds moisture and tenderness – Buttermilk enhances the texture of pancakes, cakes, and biscuits.
✔️ Boosts flavor – Its tangy taste deepens the flavor of bread, dressings, and marinades.
✔️ Acts as a meat tenderizer – Buttermilk breaks down proteins, making fried chicken and steaks more tender.
The Science Behind Buttermilk’s Tangy Taste
The signature tang of buttermilk comes from lactic acid bacteria. When milk ferments, these bacteria convert lactose (milk sugar) into lactic acid, lowering the pH and thickening the milk. This acidity is what makes buttermilk effective in baking and as a marinade.

What Type of Milk Works Best for Buttermilk?
The type of milk you use directly affects the texture, flavor, and effectiveness of homemade buttermilk. While most people use regular cow’s milk, there are several alternatives that can also work, depending on your dietary needs and recipe requirements.
Whole Milk vs. Low-Fat Milk: Which is Better?
- Whole Milk: Produces a richer and creamier buttermilk due to its higher fat content. Ideal for baked goods like biscuits and cakes where texture is important.
- Low-Fat or Skim Milk: Works just as well but results in a thinner consistency. Best for dressings, marinades, and light baking.
- Heavy Cream: Can be mixed with yogurt to create a thick, luxurious buttermilk substitute.
For best results, whole milk is the top choice when making buttermilk at home. It provides a perfect balance of fat and acidity, ensuring better texture and moisture retention in recipes.
Can You Use Plant-Based Milk to Make Buttermilk?
If you’re dairy-free or vegan, you can still make buttermilk using non-dairy milk. However, some options work better than others.
Best Plant-Based Milk Options for Buttermilk
✔️ Soy Milk – The best choice for making vegan buttermilk due to its high protein content, which reacts well with acid.
✔️ Almond Milk – Works but has a thinner consistency and mild nutty flavor.
✔️ Oat Milk – A great neutral-tasting alternative but may not thicken as much.
✔️ Coconut Milk – Can be used, but the strong coconut flavor may not be suitable for all recipes.
How to Make Vegan Buttermilk
- Choose a plant-based milk (soy milk works best).
- Add 1 tablespoon of vinegar or lemon juice per 1 cup of milk.
- Stir and let sit for 5–10 minutes until slightly thickened.
Raw Milk vs. Pasteurized Milk for Buttermilk
- Raw Milk: Can be used to make traditional buttermilk through natural fermentation, but it requires more time and careful handling to prevent harmful bacteria growth.
- Pasteurized Milk: The safest and easiest choice for making buttermilk at home. It provides consistent results and is readily available.
If using raw milk, ensure it is sourced from a trusted supplier and stored properly.

Common Buttermilk Mistakes & How to Avoid Them
Making buttermilk at home is simple, but small mistakes can affect its quality and performance in recipes. Here are the most common errors people make when preparing or using buttermilk, along with tips to avoid them.
1. Using the Wrong Vinegar Type
Not all vinegars work well for making buttermilk. Some have strong flavors that can alter the taste of your recipe.
✔️ Best Choices: White vinegar, apple cider vinegar, and lemon juice.
❌ Avoid: Balsamic, red wine, or malt vinegar, as they can add unwanted flavors.
Fix: Always use a mild acid that won’t overpower the dish. White vinegar or lemon juice is ideal for a neutral flavor.
2. Not Letting Buttermilk Sit Long Enough
When making buttermilk using milk and an acid, it needs time to curdle and thicken properly. Rushing this process can result in a mixture that is too thin and lacks the tangy taste of real buttermilk.
Fix: Let the milk and acid mixture sit for at least 5–10 minutes before using. The longer it sits, the better the consistency.
3. Choosing the Wrong Type of Milk
The type of milk you use impacts the final consistency of buttermilk.
✔️ Best Choices: Whole milk or 2% milk for a rich, creamy texture.
❌ Avoid: Skim milk, as it produces thinner buttermilk with less flavor.
Fix: If you need a thicker buttermilk, use whole milk or add a spoonful of yogurt for extra creaminess.
4. Storing Buttermilk Incorrectly
Homemade buttermilk doesn’t last as long as store-bought versions. Improper storage can lead to spoilage or separation.
✔️ Best Practices for Storage:
- Keep buttermilk in an airtight container.
- Store in the coldest part of the fridge (not the door).
- Shake before use, as separation is natural.
Shelf Life:
- Homemade buttermilk lasts up to 1 week in the fridge.
- Store-bought buttermilk can last 2–3 weeks, depending on the expiration date.
5. Can You Freeze Buttermilk?
Yes, buttermilk can be frozen, but its texture may change after thawing.
✔️ How to Freeze Buttermilk:
- Pour buttermilk into an ice cube tray or freezer-safe container.
- Freeze for up to 3 months.
- Thaw in the refrigerator and shake well before use.
Frozen buttermilk works best for baking but may separate when used in drinks or dressings.
