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. 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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a mixing bowl, cream together the sugar and butter until light and fluffy.
Add the milk and eggs, mixing well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the finely chopped walnut meats and vanilla.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

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 they set during baking.
- Butter
- Creaming with sugar traps air, giving the cake a light, tender crumb and rich flavour.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Walnut meats
- Add crunch and a nutty flavour throughout the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and stirring only until combined limits gluten development, keeping the cake tender rather than tough and dense.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour, meat, vanilla):
- Almondfits better
- Chestnutfits about as well

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