5 Best Buttermilk Substitutes for Pizza Dough

Quick tip: Use this mixture after letting it sit for 5-10 minutes to curdle; it mimics buttermilk’s acidity and moisture well without altering dough consistency.

This substitute works because the acid in lemon juice or vinegar curdles the milk, creating a similar pH and acidity level to buttermilk. The acidity helps activate baking soda or yeast, improving dough rise and tenderness. The milk provides the necessary moisture and fat content to maintain dough elasticity.

For best results, use whole or 2% milk and allow the acid to fully curdle the milk before mixing into the dough. Avoid using skim milk as it lacks fat, which can affect texture. Mix gently to avoid overworking the dough.

Compared to buttermilk, this substitute produces a very similar dough texture and rise, with only minor differences in flavor that are generally undetectable in the finished pizza crust.

Quick tip: Kefir has similar acidity and moisture to buttermilk, contributing to dough tenderness and rise with a slight tangy flavor.

Kefir is a fermented milk product with natural acidity and probiotics, which mimic the role of buttermilk in activating leavening agents and tenderizing the dough. Its liquid consistency closely matches buttermilk, maintaining proper hydration.

Use plain, unsweetened kefir to avoid unwanted flavors. Because kefir can vary in thickness, adjust flour slightly if the dough feels too wet or sticky.

The final crust will have a subtle tang similar to buttermilk dough, with good rise and chewiness, making it an excellent alternative.

Quick tip: This creates an acidic environment similar to buttermilk but without additional liquid; may slightly alter dough hydration.

Cream of tartar is an acid that, when combined with milk, lowers the pH to mimic buttermilk’s acidity. This helps activate baking soda or yeast, improving dough rise and tenderness. Since no extra liquid is added, hydration remains stable.

Mix cream of tartar thoroughly into the milk before adding to dough. Monitor dough consistency as cream of tartar can sometimes cause a slight thickening.

The resulting dough will have a similar rise and texture but may lack some of the subtle flavor complexity of true buttermilk.

Quick tip: A good dairy-free alternative that replicates acidity and moisture but may impart a mild bean-like flavor.

Soy milk curdled with an acid like lemon juice or vinegar creates a buttermilk-like substitute suitable for dairy-free diets. The acidity activates leavening agents, while soy milk provides moisture and some protein to support gluten development.

Use unsweetened soy milk to avoid sweetness altering dough flavor. Allow the mixture to sit for 5-10 minutes before use. Be cautious of slight flavor differences that may be noticeable in the crust.

This substitute produces a dough with good rise and texture, though the flavor profile may be slightly different from traditional buttermilk dough.

Quick tip: Thinned yogurt can mimic buttermilk’s acidity and moisture but requires careful adjustment to avoid overly thick dough.

Plain yogurt contains lactic acid, which helps activate leavening agents similar to buttermilk. However, yogurt is thicker, so thinning it with water approximates the consistency of buttermilk, maintaining proper hydration.

Use plain, unsweetened yogurt and mix thoroughly with water before adding to dough. Adjust flour as needed to maintain dough elasticity and avoid heaviness.

The final dough will be tender with good rise, though the flavor may be slightly tangier and the texture denser compared to using buttermilk.
