Why it works: Chocolate and sugar 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Provide structure and body, holding the icing together as it thickens.
- Grated chocolate
- Adds the chocolate flavour and firms the icing as it sets.
- Powdered sugar
- Sweetens the icing and thickens it into a spreadable consistency.
The step that matters
Beating the egg whites lightly. Overbeating egg whites makes them stiff and whitened with air, which changes the texture and stops them blending smoothly with the chocolate. Beat only until just broken up so the icing stays glossy and combines evenly.
