In this guide, you’ll learn three fast, foolproof methods to make buttermilk at home, plus tips, storage advice, and recipe ideas. Let’s get started!
How to Make Buttermilk – 3 Fast & Easy Methods
Making homemade buttermilk is easier than you think. You only need simple ingredients you probably already have in your kitchen. Here are three tried-and-tested methods:
1. Classic Method: Milk + Lemon Juice or Vinegar
This is the most popular and reliable way to make buttermilk at home. All you need is milk and an acidic ingredient like lemon juice or white vinegar.
Ingredients:
- 1 cup of milk (preferably whole or 2%)
- 1 tablespoon of lemon juice or white vinegar
Instructions:
- Pour the milk into a measuring cup or bowl.
- Add the lemon juice or vinegar.
- Stir gently and let it sit at room temperature for 10 minutes.
- You’ll notice the milk curdling slightly—that’s your homemade buttermilk.
Why it works:
The acid in the lemon juice or vinegar reacts with the milk, thickening it and giving it the tangy flavor that makes buttermilk so special. It’s perfect for baking, tenderizing meats, or adding richness to dressings.
Pro Tip: Use this method for recipes like pancakes, muffins, cakes, or cornbread.
2. Thick & Tangy: Yogurt or Sour Cream + Water
Need a richer, creamier substitute? Yogurt or sour cream works wonderfully when diluted.
Ingredients:
- ¾ cup plain yogurt or sour cream
- ¼ cup water or milk
Instructions:
- Mix the yogurt/sour cream and water until smooth.
- Use as a 1:1 replacement for buttermilk.
When to use it:
This substitute adds thickness and body, making it ideal for batters, marinades, creamy dressings, or dips.
Fun Fact: Yogurt is a probiotic powerhouse—so this version not only works great, but may also aid digestion.
3. Long-Lasting: Buttermilk Powder
If you bake often, you’ll love the convenience of buttermilk powder.
Ingredients:
- 4 tablespoons buttermilk powder
- 1 cup water
Instructions:
- Combine the powder and water until fully dissolved.
- Use immediately or refrigerate for later.
Why use it:
It has a long shelf life (up to a year unopened), doesn’t require refrigeration, and offers consistency in flavor and texture. Find it in the baking aisle or online.
