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
- Grated chocolate
- Supplies the main flavor and cocoa fat that give the paste its body.
- Corn starch
- Swells when heated with the liquid, thickening the mixture into a stiff paste.
- Eggs
- Egg yolks enrich the paste and help it set as it cooks.
- Sweet milk
- Forms the liquid base that the starch thickens into the paste.
- Sugar
- Adds sweetness and softens the bitterness of the chocolate.
The step that matters
Stir constantly while the mixture boils and thickens. Starch thickens only once it reaches a boil, and it can scorch on the bottom of the pan or form lumps if not stirred continually. Constant stirring keeps heat even and the paste smooth.
