Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
Make the custard
Bring the milk to a boil.
Mix the rice flour with some cold milk until smooth.
Once the milk boils, stir in the rice flour mixture and let it boil for 20 minutes.

Set and serve
Rinse your custard cups with cold water.
Half fill the cups with the mixture and let it cool to set.
Once cold, turn out the rice cups to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Thickens the milk as it boils, giving the custard a firm, sliceable body.
- Milk
- Forms the base of the custard and provides moisture and creaminess.
- Butter
- Adds fat for a richer, smoother mouthfeel and flavor.
The step that matters
Boiling the rice flour mixture for 20 minutes. Rice flour starch must be fully cooked in boiling liquid to thicken properly and lose its raw, floury taste. Stirring the mixture in while the milk is boiling helps prevent lumps from forming.
