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

What each ingredient does

Granulated sugar
Provides the main sweetness and forms the bulk of the candy's structure as it cooks.
Maple sugar
Adds the distinctive maple flavor and sweetness to the candy.
Sweet cream
Adds fat and richness, giving the candy a softer, creamier texture.
Glucose
Inhibits crystallization, helping the candy stay smooth rather than grainy.
English walnuts
Add crunch and nutty flavor that contrast with the smooth candy.

The step that matters

Stirring after removing from heat. Stirring while the cooked sugar cools encourages fine crystals to form, which gives a creamy, opaque texture. Stirring too early or too little can leave the candy grainy or fail to thicken properly.

Swap the walnut

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

  1. Almondfits better
  2. Pistachiofits better
  3. Chestnutfits better
  4. Walnutthe original

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