Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the batter once mixed with liquid and egg.
- Baking soda
- Reacts with the sour milk's acidity to produce gas that lightens the pancakes.
- Sour milk
- Supplies the acid that activates the baking soda and adds moisture.
- Egg
- Binds the batter and adds richness and structure as it sets.
- Sugar
- Adds sweetness and helps the surface brown during cooking.
The step that matters
Pour batter onto the griddle and let it spread until quite thin.. Batter poured too thick cooks unevenly, staying doughy inside before the outside browns. Spreading it thin lets heat reach the center so the pancake cooks through evenly.
