Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Maple sugar
Provides the sweetness and maple flavour, and dissolves into the milk to form the icing base.
Milk
Dissolves the maple sugar and, as it cooks down, thickens into a spreadable icing.
Butter
Adds fat for a smoother, richer texture and a softer mouthfeel in the finished icing.

The step that matters

Heating until thickened. Sugar and milk thicken as water evaporates and the mixture reaches the right concentration. Undercooking leaves the icing runny, while overcooking makes it stiff and grainy once it cools. Testing a spoonful in cold water shows when it is ready.

Swap the nuts

The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, milk, butter):

  1. Almondfits better
  2. Cocoafits better
  3. Pecansfits better
  4. Nutsthe original

Fit is the average pairing score against sugar, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
