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

What each ingredient does

Sugar
Forms the crisp candy base that hardens as it cools, giving the brittle structure.
Glucose
Inhibits sugar crystallisation, keeping the candy smooth and preventing it from turning grainy.
Molasses
Adds colour and a deeper, caramel-like flavour to the candy.
Popcorn
Forms the crisp body of the brittle, bound together by the candy coating.

The step that matters

Cook until the mixture reaches 300°F (150°C). Sugar syrup must reach the hard-crack stage to set brittle and crisp when cooled. Undercooked syrup stays sticky, while overcooked syrup darkens and turns bitter.

Swap the walnut

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

  1. Almondfits better
  2. Pecansfits about as well
  3. Walnutthe original
  4. Chestnutfits about as well

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