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 structure of the fudge as it cooks and sets.
- Butter
- Adds fat for a smooth, tender texture in the finished fudge.
- Molasses
- Adds depth of flavour and moisture, and helps keep the fudge soft.
- Grated chocolate
- Adds richness and a deep chocolate flavour to the fudge.
- Walnut meats
- Add crunch and nutty flavour that contrasts with the soft fudge.
- Blanched almonds
- Add crunch and nutty flavour that contrasts with the soft fudge.
The step that matters
Cook to the soft-ball stage. Sugar concentration controls the texture. Cooking too little leaves the fudge runny, while cooking too far makes it hard and grainy after cooling.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, cream, butter, chocolate, dates, walnut):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
