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

What each ingredient does

Sugar
Forms the sweet crystalline base that sets into the candy.
Cream of tartar
Acidifies the syrup, helping prevent large sugar crystals from forming.
Finely ground coffee
Adds bitter coffee flavor to the sugar mixture.
Sweet chocolate
Forms a sweet outer coating over the shaped candy balls.

The step that matters

Cooking the syrup to 242°F (117°C). Temperature controls the sugar concentration. Undercooked syrup stays soft and won't set firmly, while overcooked syrup becomes hard and brittle. Hitting the target temperature determines the final texture.
