FAQs

What does buttermilk do in baking?

It adds moisture, acidity, and helps baked goods rise when combined with baking soda.

Can I use any milk for this recipe?

Yes, but whole or 2% milk provides the best texture. Non-dairy milk also works with minor differences.

Is homemade buttermilk as effective as store-bought?

Yes, especially in baking where the acidic reaction is more important than flavor alone.

Can I drink homemade buttermilk?

You can, but it’s more acidic and less flavorful than cultured buttermilk meant for drinking.

Why is it important to let the mixture sit?

The rest time allows the acid to curdle the milk, giving it the proper texture and flavor.

Can I use cream instead of milk?

Yes, but it will produce a thicker, richer result, which may not be ideal for all recipes.

What can I use instead of lemon juice or vinegar?

Try apple cider vinegar or even cream of tartar (½ teaspoon per cup of milk).

Can I make a larger batch?

Yes. Use the same ratio: 1 tablespoon of acid for every 1 cup of milk.

What if the mixture doesn’t curdle?

It may still be usable, especially if the milk is very fresh. Stir well and use as planned.

What recipes work best with this substitute?

Pancakes, biscuits, cornbread, muffins, dressings, and fried chicken marinades are ideal.

Homemade Buttermilk is a kitchen essential you can make in minutes using just two ingredients. Whether you’re baking fluffy pancakes or tender biscuits, this simple substitute delivers the same tang and texture as the store-bought version—without an extra trip to the store.
