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 and bake
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 in the mixture and bake for 25 to 30 minutes.
Cool, fill and finish
Turn out onto sugared paper and let cool.
Cut the cake in half and spread one half with the filling mixture.
To make the filling, cream the fresh butter, gradually add icing sugar and vanilla, then stir in chopped walnuts.
Stack the two halves of the cake, trim the edges, ice with white glace icing, and 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 and richness, setting the crumb as they cook.
- Butter
- Creamed with sugar to trap air and give the cake a tender texture.
- Sugar
- Sweetens the cake and helps create a soft, tender crumb when creamed.
- Self-raising flour
- Forms the cake's structure and, with its raising agent, helps it rise.
- Chopped walnuts
- Add nutty flavour and a bit of texture to the cake crumb.
The step that matters
Stir in the flour quickly and lightly. Once flour meets liquid, gluten begins to form, so overmixing makes the cake tough and dense. Folding gently keeps the crumb light and tender.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, butter, vanilla, flour):

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