Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Baking soda
Reacts with the sour milk's acid to produce gas, helping the pancakes rise and turn light.
Sour milk
Its acidity activates the baking soda and adds a slight tang while keeping the batter moist.
Egg
Binds the batter and adds structure and richness to the pancakes.
Flour
Provides the main structure that sets as the pancakes cook.

The step that matters

Beating the baking soda into the sour milk and flour. Baking soda needs acid to release carbon dioxide, so it should be dissolved in the sour milk and mixed in promptly. Gradual addition and smooth beating spread the gas evenly so the batter rises consistently rather than in pockets.
