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

What each ingredient does

Sugar: Forms the hard, brittle candy base as it cooks to the hard crack stage.
Glucose: Slows sugar crystallization, helping the candy stay smooth and prevent graininess.
Nut meat: Adds bulk, flavor, and crunch to the candy matrix.

The step that matters

Boil to 280°F (140°C) hard crack stage. Cooking the sugar syrup to the hard crack stage removes enough water that the candy sets hard and brittle when cooled. Undercooking leaves it sticky and soft, while overcooking can make it bitter or burnt.

Swap the nuts

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