Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Directions
Make the sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main chocolate flavour and some body as the sauce thickens.
- Sugar
- Adds sweetness and helps the sauce thicken into a syrupy texture.
The step that matters
Cook slowly until it thickens. Gentle heat lets the sugar and chocolate dissolve fully and thicken gradually. Cooking too hard can scorch the sugar or chocolate, and cooking too briefly leaves the sauce thin.
