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
- Tapioca
- Swells during soaking and cooking to thicken the custard into a soft, pudding-like texture.
- Milk
- Provides the liquid base and richness that the tapioca thickens.
- Egg yolks
- Add richness and help thicken and enrich the custard as it cooks.
- Egg whites
- Whipped and folded in, they add lightness and airiness to the finished custard.
- Sugar
- Adds sweetness and balances the flavour of the milk and eggs.
The step that matters
Cooking the custard in the double boiler. Egg yolks can curdle or scramble if overheated. Gentle, indirect heat in a double boiler lets the custard thicken smoothly while the tapioca softens fully.
