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 ↓
Miriam's Fudge
Ingredients
Directions
Make the fudge
In a saucepan, combine chocolate, sugar, and water.
Bring to a boil, then add butter and do not stir.
When a drop forms a soft ball in cold water, remove from heat and let cool until cold to the touch.
Shape and serve
Stir in vanilla and nuts if desired until the candy crumbles.
Transfer to a buttered board.
Knead with your hands for five minutes.
Form into three long rolls, about 1 inch high.
Slice into ½ inch pieces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves and forms the crystal structure that sets the fudge's texture as it cools.
- Baker's chocolate
- Provides the chocolate flavor and fat that give the fudge its rich body.
- Butter
- Adds fat that makes the fudge smoother and more tender.
- Water
- Dissolves the sugar so it can be boiled into a syrup before cooling.
The step that matters
Let the mixture cool before kneading. Stirring or kneading while the syrup is still hot encourages large sugar crystals to form, making the fudge grainy. Cooling until cold to the touch lets the sugar crystallize into fine crystals for a smooth, creamy texture.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (chocolate, sugar, butter, egg, vanilla):
- Almondfits better
- Pecansfits better
- Hazelnutfits better
- Nutsthe original
Fit is the average pairing score against chocolate, sugar, butter, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
