Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk or cream
- Provides the liquid base and richness for the custard.
- Egg yolks
- Thicken the custard as they set when gently heated, giving it body.
- Gelatine
- Sets the liquid so the rum cream holds its shape when unmolded.
- Rum
- Adds its distinctive flavour and aroma to the cream.
The step that matters
Stir the egg yolk mixture over low heat. Egg yolks thicken through gentle heat, but if they get too hot they scramble and turn grainy. Low heat and steady stirring keep the custard smooth.
