Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
No. 8 Fudge
Ingredients
Directions
The book gives no oven temperature. The 236°F (113°C) in the steps was added when the recipe was transcribed, as a starting point.
In a large pot, combine sugar, glucose, cream, butter, and salt.
Cook the mixture until it reaches 236°F (113°C).
Remove from heat and add the bitter chocolate and fondant.
Stir until dissolved and the mixture begins to show grain.
Pour onto a paper-lined board or slab to cool.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 cools and sets.
- Glucose
- Interferes with sugar crystallization, keeping the fudge smoother and less grainy.
- Cream
- Adds moisture and fat, giving the fudge a soft, rich texture.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Bitter chocolate
- Provides chocolate flavor and deep color.
- Fondant
- Adds fine sugar crystals that encourage a smooth, creamy set.
The step that matters
Stir until the mixture begins to show grain. Stirring after cooking to temperature controls crystal formation. Stir too early or too little and the fudge may stay soft or set unevenly; stir too late and it sets too firm and grainy.
