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 ↓

What each ingredient does
- Cake chocolate
- Provides the main chocolate flavour and, as it cools, a firm, glossy set.
- Confectioners' sugar
- Thickens the melted chocolate and sweetens it so it can be spread.
- Vanilla
- Adds aroma that rounds out and deepens the chocolate flavour.
The step that matters
Add 1 teaspoon vanilla and keep warm, but do not boil.. Chocolate can seize and turn grainy when overheated, and too much heat thins the icing so it runs off instead of staying on the cake. Keeping it warm but below boiling keeps it smooth and spreadable.
