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

Maple sugar
Adds maple flavor and sweetness to the icing.
Brown sugar
Adds sweetness and molasses flavor, and helps the icing set as it cools.
Butter
Adds fat for a smooth, rich texture in the finished icing.
Milk
Dissolves the sugars and provides the liquid that boils down into the icing.
Chopped pecan nuts
Adds crunch and a toasty, nutty flavor to the icing.

The step that matters

Boil until it shreds off a spoon. Sugar syrup must reach the right concentration to set properly. Boiling too briefly leaves the icing runny, while overcooking makes it grainy or hard. The spoon test shows when the sugar has thickened enough.

Swap the nuts

How well each one fits the dish's main ingredients (sugar, butter, milk, vanilla):

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

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