Why it works: Milk and rice are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,374 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the milk as they set into a smooth, custard-like texture.
- New milk
- Forms the liquid base of the custard and carries its richness.
- Rice
- Gives the custard body and a soft, starchy bite.
- Loaf sugar
- Adds sweetness to balance the richness of the milk and eggs.
The step that matters
Boil for no longer than 1 minute, stirring constantly. Egg proteins set when heated, so the custard can curdle or turn grainy if it boils too long or the mixture is not kept moving. A brief boil with constant stirring keeps it smooth.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, rice, sugar):
- Cinnamonfits better
- Nutmegthe original
- Turmericfits less well
- Gingerfits less well
Fit is the average pairing score against milk, egg, rice, sugar. Candidates are from the same food group and used in at least 100 recipes.
