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

What each ingredient does

Sour milk
Provides acidity that reacts with baking soda to make the fritters rise and tender.
Egg
Binds the batter and adds structure as it sets in the hot oil.
Flour
Thickens the batter and gives the fritters their body once cooked.
Baking soda
Reacts with the sour milk's acid to release gas, lifting the batter for a lighter texture.
Melted butter
Adds fat for richness and helps the fritters brown.

The step that matters

Stir in baking soda until well mixed. Baking soda reacts with acid in the sour milk immediately, releasing gas. Mixing it in evenly and frying soon after keeps the batter lifting, so fritters stay light instead of flat.
