Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ingredients
Directions
Make the filling

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
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 that the starch thickens into a smooth, pourable custard.
- Sugar
- Sweetens the filling and adds body to the custard as it cooks.
- Cornstarch
- Thickens the milk mixture as its starch granules swell with heat, giving a set filling.
- Baker's chocolate
- Adds chocolate flavor and richness, and firms the filling as it cools.
The step that matters
Thickening the milk, sugar, and cornstarch in the double boiler. Cornstarch only thickens fully once it reaches a high enough temperature, and the gentle heat of a double boiler helps prevent scorching. Stirring keeps the starch evenly dispersed so the filling does not form lumps.
