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

What each ingredient does

Sugar
Dissolves in water and hardens into a brittle, crisp candy coating as it cooks.
English walnuts
Add crunch and a toasty, nutty flavor that contrasts with the sweet coating.
Brazil nuts
Add rich, buttery crunch and bulk to the candied mix.

The step that matters

Remove from heat immediately at the crackle stage. Sugar syrup darkens and turns bitter quickly once it passes the crackle stage, so pulling it off the heat at the right moment keeps the candy light in color and flavor.

Swap the pineapple

How well each one fits the dish's main ingredients (sugar, walnut, brazil nut, orange):

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Pineapplethe original

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