Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Walnut Cake
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Beat in the eggs one at a time.
Add the vanilla and chopped walnuts.
Sift the flour and stir it quickly and lightly into the mixture.
Grease and line a Yorkshire pudding tin.
Pour the mixture into the tin and bake for 25 to 30 minutes.
Cool, fill and finish
Turn the cake out onto sugared paper and let it cool.
Once cool, cut the cake in half horizontally.
For the filling, cream the butter, then gradually add the icing sugar and vanilla.
Stir in the chopped walnuts and spread on one half of the cake.
Place the other half on top, trim the edges, and ice with white glace icing.
Decorate with walnut halves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure as they set and trap air, forming the cake's crumb.
- Butter
- Creamed with sugar to trap air and add richness and a tender texture.
- Sugar
- Sweetens the cake and helps create a light, aerated batter when creamed.
- Self-raising flour
- Provides the flour structure and, with its raising agent, helps the cake rise.
- Walnuts
- Add crunch and a nutty flavour to the cake and filling.
The step that matters
Stir in the flour quickly and lightly. Overmixing once flour is added develops gluten, making the cake tough and dense instead of tender. Sifting and folding gently keeps the crumb light.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, butter, vanilla):
- Almondfits better
- Pecansfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against egg, sugar, butter, vanilla. Candidates are from the same food group and used in at least 100 recipes.
