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 ↓
Walnut 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 batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
Stir in the milk.
In a separate bowl, combine the flour and baking powder, then gradually add to the butter mixture.
Fold in the broken walnuts.
In another bowl, beat the egg whites until stiff peaks form, then gently fold into the batter.
Bake
Pour the batter into a greased sheet pan and bake for 45 minutes.
Make the frosting and finish
For the frosting, boil the sugar and water until it threads.
Slowly pour the hot syrup into the beaten egg white while mixing.
Beat until cool, add vanilla, and spread 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
- Provides the starch and gluten network that gives the cake its structure.
- Egg whites
- Whipped to stiff peaks, they trap air that lifts the batter and makes it light.
- Egg yolks
- Add richness and emulsify with the butter, helping the batter hold together.
- Butter
- Creamed with sugar to trap air and add tenderness and richness.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Sugar
- Adds sweetness, helps tenderize the crumb, and keeps the cake moist.
The step that matters
Folding in the beaten egg whites. The whites' foam holds the air that lifts the batter. Folding gently keeps that air in; vigorous stirring deflates the foam and leaves a denser cake.
Swap the walnut

Fit is the average pairing score against butter, sugar, egg, milk, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
