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 white
- Whipped into a foam that traps air, giving the frosting its light, spreadable body.
- Chocolate
- Provides the chocolate flavour and, once melted in, adds richness and body to the frosting.
- Sugar
- Sweetens the frosting and, as it is added, helps the foam hold its shape and stiffen.
The step that matters
Beat the egg white to a stiff froth. The egg white foam must be whipped until it holds firm peaks, because that trapped air gives the frosting its structure. Under-beaten white stays runny, while over-beaten white turns dry and grainy and loses its ability to hold the chocolate and sugar.
