Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Maple sugar
- Provides the main sweetness and flavour, and sets the icing's texture as it cools and is whipped.
- Milk or cream
- Dissolves the sugar and adds moisture, so the icing stays smooth rather than grainy.
- Butter
- Adds fat that makes the icing richer and softer on the palate.
The step that matters
Boil for ten minutes, stirring constantly in the same direction. Sugar mixtures can scorch on the bottom of the pan or boil over if left unattended. Constant stirring spreads the heat evenly and keeps the sugar dissolved, which helps prevent grainy crystals and burnt flavour in the finished icing.
