Why it works: Corn and walnut match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 349 recipes. Both carry 2-nonenal, which smells fatty, green. 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.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the water, flour, corn starch, baking powder, and lemon flavoring to the batter. Mix the batter well.
Beat the egg whites in a separate bowl until stiff peaks form. Fold the beaten egg whites into the batter.
Pour the batter into prepared cake pans and bake the cakes until golden.
Make the walnut filling
Combine the light brown sugar and water in a saucepan for the filling. Boil the mixture until it threads.
Stir in the egg whites. Beat the mixture until creamy.
Fold in the chopped walnuts.
Assemble
Use the walnut mixture as filling between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake its light, airy structure.
- Butter
- Creaming with sugar traps air and adds richness and tenderness to the crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises.
- Light brown sugar
- Dissolved and boiled with water to form the sweet, thick filling base.
- English walnuts
- Add texture and nutty flavor to the filling.
The step that matters
Boil the filling syrup until it threads. Sugar syrup must reach the right concentration; underheating leaves the filling runny, while overheating makes it hard and grainy once it cools.
