Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
English 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg whites until stiff.
In another bowl, cream the butter and sugar together until light and fluffy. Add the milk to the butter mixture and mix well.
Sift the flour and baking powder together, then gradually add to the wet ingredients.
Fold in the beaten egg whites gently.
Bake and ice
Divide the batter into three layers and bake until golden.
For icing, mix confectioner's sugar with a little water to achieve a spreadable consistency.
Layer the icing between the cake layers and on top, then sprinkle with broken walnut meats.
Decorate the top with whole walnut meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam that gives the cake its light, airy structure.
- Butter
- Creamed with sugar to trap air and add richness and tender texture.
- Sugar
- Creamed with butter to aid aeration and add sweetness and browning.
- Flour
- Forms the cake's main structure once mixed with the liquids.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Milk
- Adds moisture and helps hydrate the flour into a smooth batter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only while whole; overmixing or stirring vigorously deflates the foam, leaving dense layers instead of a light cake.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, flour, meat):
- Almondfits better
- Walnutthe original
- Pecansfits about as well
- Chestnutfits about as well
Fit is the average pairing score against egg, sugar, butter, milk, flour, meat. Candidates are from the same food group and used in at least 100 recipes.
