Why it works: Milk and rum work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 967 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the filling and carries the other ingredients.
- Chopped walnuts
- Add nutty flavour and a bit of texture to the filling.
- Egg yolks
- Thicken the filling as their proteins set with gentle heat, and add richness.
- Cornstarch
- Thickens the liquid as its starch granules swell and gelatinize when heated.
The step that matters
Thickening with the egg yolks and cornstarch. Egg yolk proteins set with gentle heat and can curdle if the mixture gets too hot or is not stirred. Cornstarch needs to heat fully to reach its full thickness, so the filling should be stirred over steady heat until it is smooth and thickened.
Swap the walnut
How well each one fits the dish's main ingredients (milk, egg, rum):
- Pecansfits better
- Cocoafits about as well
- Almondfits about as well
- Walnutthe original
Fit is the average pairing score against milk, egg, rum. Candidates are from the same food group and used in at least 100 recipes.
