Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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 custard that thickens when heated.
- Egg yolks
- Thicken the custard and add richness through their proteins setting with heat.
- Cornstarch
- Thickens the milk mixture as its starch swells and gels when heated.
- Sugar
- Sweetens the filling and helps keep the custard smooth.
The step that matters
Cooking the custard over hot water until thickened. Egg yolks and cornstarch thicken only with gentle heat. Overheating can scramble the yolks or leave the starch lumpy, so the custard should be cooked slowly over hot water, not boiled hard.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
