Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides the sweet, crystalline base that sets into the fudge's firm body as it cooks.
- Cream
- Adds fat and moisture, giving the fudge a smooth, creamy texture.
- Butter
- Contributes richness and fat, softening the texture of the finished fudge.
- Sweet chocolate
- Adds deep flavor and fat, helping the fudge set smooth and rich.
- Fondant
- Adds extra sugar that dissolves in the hot mixture, helping keep the fudge smooth.
- Ground english walnuts
- Add crunch and nutty flavor that contrast with the soft fudge.
The step that matters
Cooking to soft ball stage (236°F). Sugar concentration determines how the fudge sets. Undercooking leaves it soft and runny, while overcooking makes it hard and grainy. Hitting the stated temperature gives the right firmness.
