Why it works: Fig and walnut match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 373 recipes. Both carry 2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and forms the crystal structure that sets the fudge as it cooks and cools.
- Butter
- Adds fat for a smooth, tender texture and rich mouthfeel.
- Chocolate
- Adds chocolate flavour and richness, and fat that softens the set.
- Milk
- Adds moisture and milk solids for a creamy texture.
- Molasses
- Adds moisture, deeper colour and a robust, slightly bitter sweetness.
The step that matters
Boiling for the full time. The boiling time concentrates the sugar syrup and controls how firm the fudge sets. Stopping early leaves it soft and sticky, while cooking too long makes it hard and grainy.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, milk, molasses, butter, chocolate, fig, raisin):
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
- Pecansfits about as well
Fit is the average pairing score against sugar, milk, molasses, butter, chocolate, fig, raisin. Candidates are from the same food group and used in at least 100 recipes.
