Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ingredients
Directions
Make the candy
Combine sugar, cream, and cold water in a hot water pan of a chafing dish.
Stir until sugar melts.
When the mixture begins to bubble, stir in cocoa or chocolate.
Let it boil for exactly 6 minutes with the flame at half strength.
After 6 minutes, add butter.
Stir well, ensuring the candy doesn't stick to the pan.
After the butter has boiled for 3 minutes, extinguish the flame.
Add vanilla.
Finish and set
Beat the candy until it thickens rapidly, about 1 minute.
Pour into a buttered tin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Provides sweetness and, as it dissolves and cooks, forms the crystalline structure of the fudge.
- Cream
- Adds fat and richness, giving the fudge a softer, creamier texture.
- Cocoa or chocolate
- Supplies the chocolate flavour and colour of the fudge.
- Butter
- Adds fat for smoothness and a tender, glossy texture.
The step that matters
Beat the candy until it thickens rapidly. Beating while the cooked sugar mixture cools controls crystal formation. Too little beating leaves the fudge soft and runny, while beating too long or after it has set can make it grainy and hard to pour.
Swap the cocoa
How well each one fits the dish's main ingredients (sugar, cream, butter, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Cocoathe original
Fit is the average pairing score against sugar, cream, butter, vanilla. Candidates are from the same food group and used in at least 100 recipes.
