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 Cakes
Ingredients
Directions
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Sift together the flour and baking powder.
Make the batter
Cream the butter and sugar until light and fluffy.
Add the egg yolks and mix well.
Stir in the chopped walnuts, lemon rind, and vanilla essence.
Gradually sift in the flour, adding milk as needed to keep the mixture smooth.
Gently fold in the beaten egg whites until just combined.
Pour the mixture into a greased cake tin, filling it halfway.
Bake and finish
Bake for 1½ to 2 hours until golden and a skewer comes out clean.
Cool on a wire rack, then spread with soft icing and garnish with walnuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it sets.
- Butter
- Adds richness and a tender crumb when creamed with sugar.
- Caster sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Egg yolks
- Add richness, moisture and binding to the batter.
- Egg whites
- Whipped to stiff peaks, they give the cake lift and an airy texture.
- Walnuts
- Add crunch and a toasty, nutty flavour throughout the cake.
The step that matters
Folding in the egg whites. Whites hold air only while whipped, so fold gently and just until combined; overmixing knocks the air out and leaves a dense cake.
