Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid as its starch swells and sets when heated.
- Egg
- Adds body and richness as its proteins set during heating.
- Buttermilk
- Provides the liquid base and a tangy, slightly acidic flavor.
- Sugar
- Adds sweetness that balances the tang of the buttermilk.
The step that matters
Stir the mixture on the stove until it boils. Egg proteins can curdle or scramble if heated unevenly or too fast, and flour starch needs to reach a boil to thicken fully. Constant stirring keeps the heat even and the mixture smooth.
