Why it works: Milk and flour 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
- Egg yolk
- Thickens the custard and adds richness as it cooks.
- Flour
- Thickens the filling as it cooks with the milk.
- Milk
- Forms the liquid base that becomes the creamy filling.
- Sugar
- Sweetens the filling and balances the lemon flavoring.
The step that matters
Stirring the mixture into the hot milk and cooking until thickened. Flour and egg yolk thicken the filling only as they heat, and stirring constantly prevents lumps and scorching on the bottom of the pan.
Swap the lemon
How well each one fits the dish's main ingredients (milk, sugar, egg, flour):
