Easy homemade buttermilk substitute made with milk and vinegar or lemon juice. Ready in 5 minutes, this simple kitchen hack is perfect for pancakes, waffles, biscuits, cakes, and fried chicken recipes when you don’t have store-bought buttermilk on hand.

Ingredients

1 tablespoon white vinegar or fresh lemon juice (15 ml)
1 scant cup milk (240 ml)

Instructions

Step 1: Prepare the Mixture

Add the vinegar or lemon juice to a measuring cup.

Step 2: Add the Milk

Fill the measuring cup with milk until it reaches the 1-cup mark.

Step 3: Let It Rest

Stir gently, then let the mixture sit at room temperature for about 5 minutes. The milk will slightly curdle and thicken, creating the tangy flavor and texture of buttermilk.

Tips

Use whole milk for a richer, creamier result.
Allow the mixture to rest fully; this gives it the best texture and tang.
If the milk doesn’t curdle much, don’t worry—it will still work in recipes.
For baking, always measure the buttermilk after it has rested.

Variations and Substitutions

Vinegar Options: Use apple cider vinegar instead of white vinegar for a milder taste.
Citrus Choice: Lemon juice or lime juice both work well.
Dairy-Free: Combine 1 tablespoon vinegar or lemon juice with 1 cup soy milk or almond milk to make a vegan version.
Yogurt Alternative: Mix plain yogurt with a splash of milk for a thicker substitute.

FAQs

Can I make buttermilk ahead of time?
Yes, you can prepare it in advance and store it in the refrigerator for up to 3 days. Stir before using.

What if I don’t see curdling?
Even if it doesn’t look very curdled, the acidity is there and will still activate leavening agents in baking.

Can I use skim milk?
Yes, but whole milk provides the best flavor and texture.

Is this the same as store-bought buttermilk?
Not exactly. Store-bought buttermilk is cultured, while this version is a quick substitute that works just as well for baking.

Serving Suggestions

Use in pancakes, waffles, muffins, and cakes for extra fluffiness.
Add to fried chicken marinades for tender and juicy meat.
Stir into salad dressings for a tangy flavor.
Use in biscuits or scones for a light, airy texture.
