Why it works: Cream and rum work together. They rank in the top 18% of all ingredient pairs, and cooks put them together in 842 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Directions
Make the custard
Scald half of the cream with the cold water.

Cream and egg barely smell alike, yet cooks put them together in 42,166 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds richness and fat, giving the frozen punch a smooth, creamy texture.
- Egg yolk
- Thickens the custard as its proteins set with gentle heat, adding body and richness.
- Rum
- Adds aroma and flavor, and alcohol softens the frozen texture by lowering the freezing point.
- Saccharine
- Provides sweetness without adding sugar.
The step that matters
Thickening the egg yolk over hot water. Egg proteins set with heat, so cooking gently and stopping as soon as the mixture thickens prevents it from curdling into grainy lumps.
