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
- Fine flour
- Thickens the milk as its starch swells and sets during gentle cooking.
- New milk
- Forms the liquid base that the flour thickens into a smooth custard-like caudle.
- Sugar
- Adds sweetness to the milk base.
The step that matters
Pour the flour mixture into the boiling milk. Flour mixed smooth with water and added to hot milk disperses evenly, so the starch thickens without lumps forming. Keep the milk boiling as you pour and stir steadily.
