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 ↓
Quick Fudge Icing or Candy
Ingredients
Directions
Make the syrup
Mix sugar and cocoa in saucepan.
Stir in butter, milk, and corn syrup.
Bring to a boil.
Boil for 3 minutes, stirring occasionally.
Cool and finish the icing
Take out the spoon and set the pan in cold water.
When you can hold your hand on the bottom of the pan, the syrup is cool enough.
Stir in 1 ½ cups confectioners' sugar and vanilla.
Add an additional ½ cup of confectioners' sugar if needed.
Stir the icing until thick enough to spread.
Add more confectioners' sugar or milk if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the icing and, when boiled, forms the syrup base that sets as it cools.
- Butter
- Adds fat for a smooth, rich texture and mouthfeel.
- Milk
- Dissolves the sugar and adds moisture so the icing can be spread.
- Light corn syrup
- Interferes with sugar crystallization, keeping the icing smooth rather than grainy.
- Confectioners' sugar
- Thickens the cooled syrup into a spreadable icing and adds sweetness.
The step that matters
Cooling the syrup before beating in sugar. Beating in confectioners' sugar while the syrup is still hot makes the icing thin and can leave it grainy. Letting the pan cool until the bottom feels comfortably warm lets the mixture thicken into a smooth, spreadable icing.
Swap the cocoa
How well each one fits the dish's main ingredients (sugar, butter, milk, corn, syrup, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Cocoathe original
Fit is the average pairing score against sugar, butter, milk, corn, syrup, vanilla. Candidates are from the same food group and used in at least 100 recipes.
