Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Boiled Rice Dumplings, Custard Sauce
Ingredients
Directions
Make the dumplings
Boil the rice until tender, then drain and mash it moderately fine.
Mix in the butter, sugar, mixed spice, salt, and egg yolks.
Moisten the mixture with 1-2 tablespoons of cream.
Shape the mixture into balls with floured hands and tie them in floured pudding cloths.
Steam or boil the dumplings for 40 minutes.
Make the custard sauce
For the custard sauce, mix the sugar and slightly warmed butter.
Beat the egg yolks and cream together, then combine with the sugar and butter mixture.
Place the sauce in a double saucepan set in hot water and whisk for 3 minutes.
Transfer the saucepan to cold water and whisk until the sauce cools.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the dumplings, giving them their body and soft, starchy texture.
- Butter
- Adds fat and richness, softening the mixture and giving a smooth mouthfeel.
- Egg yolks
- Bind the mixture and enrich the custard sauce, which thickens as the yolks gently cook.
- Cream
- Adds moisture and richness, loosening the dumpling mix and smoothing the custard.
- Sugar
- Adds sweetness and helps give the custard sauce a smooth, rounded flavour.
The step that matters
Whisking the custard over hot water. Egg yolks thicken gently at moderate heat. If the water is too hot or the sauce is left unwhisked, the yolks can scramble and turn grainy. Cooling it promptly and whisking keeps the sauce smooth.
