Name: Chocolate Cocoanut Fudge Basis
Ingredients: 25 lbs mixed scrap; water (enough to dissolve); cocoa (to flavor); vanilla (to flavor); burnt sugar (to color, if necessary); 5 lbs scrap fondant; 2 lbs chip coconut

Why it works: Vanilla and coconut match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,294 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Chocolate Cocoanut Fudge Basis

Ingredients

Directions

Make the base

Place mixed scrap in a kettle and add enough water to dissolve.
Boil until melted, then strain.
Cook to 248°F (120°C), stirring and rubbing the sides of the kettle with a paddle.
Add cocoa, vanilla, and burnt sugar for color if needed.

Finish and set

When thick, add scrap fondant and mix until smooth.
Stir in chip coconut and pour into a paper-lined tray.
Let set overnight, then turn out and cut into 2×4 bars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mixed scrap: Forms the sugar and fat body of the fudge, giving it its base structure and sweetness.
Scrap fondant: Adds fine sugar crystals that help the fudge set smooth and creamy rather than grainy.
Cocoa: Provides the chocolate flavor and deepens the color of the fudge.
Chip coconut: Adds chewy texture and coconut flavor throughout the set fudge.

The step that matters

Cook to 248°F (120°C) while stirring. Cooking to this temperature sets the sugar concentration that determines firmness when the fudge cools. Stirring and rubbing the sides of the kettle helps prevent sugar crystals from forming, which would make the fudge grainy.
