Why it works: Vanilla and milk 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. 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the chopped walnuts.
If using, dissolve the grated chocolate in a little milk and add to the batter.
Bake and finish
Pour the batter into a buttered cake tin.
Bake for about 30-35 minutes or until a toothpick inserted in the center comes out clean.
Let cool, then ice and decorate with almonds.

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 and richness as they set in the oven.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps the creamed mixture hold air for a light texture.
- Flour
- Forms the structure of the cake as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises.
- Chopped walnuts
- Add crunch and a nutty flavor throughout the cake.
The step that matters
Mixing the dry ingredients into the wet mixture. Mixing only until just combined keeps the batter from overdeveloping the flour's gluten, which would make the cake tough and dense.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, vanilla, chocolate, milk):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against egg, sugar, butter, flour, vanilla, chocolate, milk. Candidates are from the same food group and used in at least 100 recipes.
