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 ↓
Fudge
Ingredients
Directions
Make the fudge
Melt the semi-sweet chocolate with a little water over low heat.
Remove from heat and beat in the Philadelphia Cream Cheese until smooth.
Add the sifted confectioners' sugar, dash of salt, and vanilla; mix well.
Stir in the raisins and chopped nuts.
Set and cut
Press the mixture into a buttered pan.
When cold, cut into squares.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Semi-sweet chocolate
- Melts into the base and provides the rich chocolate flavor and smooth body.
- Philadelphia cream cheese
- Adds creaminess and tang that softens the fudge texture.
- Confectioners' sugar
- Dissolves into the mixture to sweeten and firm up the fudge.
- Raisins
- Add chewy texture and natural sweetness throughout the fudge.
- Chopped nuts
- Add crunch and contrast to the soft, creamy base.
The step that matters
Remove from heat before beating in the cream cheese. Melted chocolate can seize or turn grainy if overheated, and cream cheese blends smoothly only into warm, not scorching, chocolate. Taking the pan off the heat first keeps the mixture silky.
Swap the raisin
How well each one fits the dish's main ingredients (chocolate, cream cheese, sugar, vanilla, nuts, butter):
- Coconutfits better
- Bananafits better
- Pineapplefits better
- Raisinthe original
Fit is the average pairing score against chocolate, cream cheese, sugar, vanilla, nuts, butter. Candidates are from the same food group and used in at least 100 recipes.
