Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Fudge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together in a bowl.
Add the milk and mix well.
Sift the baking powder with the flour and gradually add to the mixture.
Stir in the melted chocolate and coarsely chopped walnuts.
Beat the egg yolks and whites separately, then fold them into the batter.
Bake and make the frosting
Pour the batter into a greased cake pan and bake for about 30-35 minutes.
For the frosting, melt the butter in a saucepan.
Add the chocolate, sugar, salt, and milk, then bring to a boil for 8-10 minutes.
Remove from heat, stir in the vanilla, and beat until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to create a tender, aerated crumb and adds richness.
- Eggs
- Separated and folded in to add structure and lift to the batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Flour
- Provides the structure that holds the cake together as it sets.
- Chocolate
- Adds chocolate flavor and color to both the cake and the frosting.
- Sugar
- Sweetens the cake and, when creamed, helps trap air for a lighter texture.
The step that matters
Beating the egg whites and folding them in. Whites beaten separately and folded gently keep air in the batter. Stirring them in hard knocks that air out, leaving a denser cake.
Swap the walnut
How well each one fits the dish's main ingredients (chocolate, sugar, egg, butter, milk, flour, vanilla):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against chocolate, sugar, egg, butter, milk, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
