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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat in the eggs one at a time, adding a little flour to prevent curdling.
Stir in the chopped walnuts, remaining flour, baking powder, and salt.
If the batter is too thick, add a little milk to reach the desired consistency.
Pour the batter into a greased cake pan.
Bake and finish
Bake for 1.5 hours or until a toothpick inserted in the center comes out clean.
Once cooled, decorate with glacé icing and additional walnuts or butter icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich texture.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Sugar
- Creamed with butter to aerate the batter and add sweetness and browning.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Walnuts
- Add nutty flavour and a bit of crunch throughout the cake.
The step that matters
Adding the eggs one at a time. Eggs added too quickly can curdle the creamed butter and sugar, breaking the emulsion. Adding a little flour with each egg helps keep the batter smooth and stable so the cake bakes evenly.
Swap the walnut
How well each one fits the dish's main ingredients (flour, sugar, butter, milk, vanilla, egg):
- Almondfits better

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