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

What each ingredient does

Egg whites
Whipped into stiff foam that traps air and gives the candy its light, airy structure.
Sugar
Cooked into a syrup that sets firm as it cools, giving the candy its body and sweetness.
Cream of tartar
Acidifies the syrup, helping prevent sugar crystallisation and keeping the foam stable.
Chopped nut meats
Add crunch and nutty flavour on the base and top of each piece.
Melted chocolate
Forms a sweet, glossy coating that adds flavour and contrast to the foam.

The step that matters

Boil the syrup to the hard ball stage. Sugar syrup must reach the right concentration; undercooked syrup stays soft and won't set, while overcooked syrup turns brittle or sugary. Judging the stage accurately controls the final texture.
