The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the icing and, as it cooks, caramelizes to give a deeper flavor and color.
- Grated maple sugar
- Adds maple flavor and sweetness that carries the caramel notes.
- Butter
- Adds fat for a smooth, rich texture and mouthfeel in the finished icing.
- Milk
- Provides liquid that dissolves the sugars and helps form a creamy, spreadable texture.
The step that matters
Boil the mixture for 13 minutes. Sugar syrups thicken as water evaporates and temperature rises, so boiling for the full time sets the texture. Too short leaves the icing runny; too long can make it grainy or hard once it cools.
