Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides rich chocolate flavor and fat that give the fudge its smooth body.
- Sugar
- Adds sweetness and, as it concentrates during cooking, helps the fudge set firm.
- Molasses
- Adds moisture, deep sweetness, and color, and helps keep the fudge soft.
- Milk
- Adds moisture and dairy richness, producing a creamier texture.
- Butter
- Adds fat that makes the fudge tender and smooth.
The step that matters
Cook until nearly done. Cooking drives off water and concentrates the sugars, which sets the fudge's texture. Stopping too early leaves it soft and sticky, while cooking too long can make it hard or grainy.
