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

What each ingredient does

Sour milk
Its acidity reacts with the baking soda to produce gas that lifts the biscuits.
Baking soda
Reacts with the acid in sour milk to release carbon dioxide, which makes the biscuits rise.
Flour
Provides the structure that holds the biscuits together as they set in the oven.
Sugar
Adds sweetness and helps the biscuit tops brown as they bake.

The step that matters

Stir in the flour until just combined. Overmixing the batter develops gluten, which makes the biscuits tough. Mixing only until the flour is incorporated keeps them tender while the baking soda lifts them.
