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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, mix melted chocolate and butter until smooth.
Add sugar, milk, and vanilla; stir until combined.
In another bowl, whisk flour and baking powder together.
Gradually add the dry ingredients to the chocolate mixture, mixing well.
Fold in the chopped walnuts.
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Make the frosting and finish
For the frosting, combine melted chocolate, butter, and milk in a bowl.
Gradually add confectioner's sugar, mixing until smooth.
Spread the frosting over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake crumb as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and turns light.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
- Eggs (in the method)
- Not listed in this recipe; omitted.
The step that matters
Gradually add the dry ingredients to the chocolate mixture, mixing well.. Adding flour in portions and mixing only until combined keeps the batter smooth and prevents lumps. Overmixing develops gluten in the flour, which can make the cake tough.
Swap the walnut
How well each one fits the dish's main ingredients (chocolate, butter, sugar, milk, flour, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Walnutthe original
Fit is the average pairing score against chocolate, butter, sugar, milk, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
