Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Provides sweetness and helps the fudge set firm as it cools.
- Brown sugar
- Adds sweetness and moisture, with molasses giving a deeper flavor and softer texture.
- Molasses
- Adds moisture, deep flavor, and helps keep the fudge soft.
- Sweet chocolate
- Supplies the chocolate flavor and fat that give fudge its richness.
- Sweet milk
- Adds liquid and milk solids that contribute to a creamy texture.
- Nuts
- Add crunch and a contrasting texture to the soft fudge.
The step that matters
Beating until it begins to cream. Beating the hot syrup as it cools causes sugar to crystallize into fine crystals, giving a smooth, creamy texture. Beating too early or too late changes the result.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, molasses, chocolate, milk, butter):
- Almondfits better
- Peanutfits about as well
- Pecansfits about as well
- Nutsthe original
Fit is the average pairing score against sugar, molasses, chocolate, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
