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 ↓

Make the custard

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet milk
- Forms the liquid base of the custard that sets when heated.
- Chocolate
- Melts into the milk to give the custard its flavor and color.
- Egg yolks
- Thicken the custard as they heat and give it richness.
- Cornstarch
- Thickens the custard so it holds its shape when cut.
The step that matters
Cooking the custard while stirring constantly. Egg yolks can curdle or turn grainy if they overheat in one spot. Constant stirring spreads the heat evenly so the starch and yolks thicken the custard smoothly.
