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 moderate 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).
Make the batter
Beat the butter and sugar together until creamy.
Sift in the flour and mix well.
Add the chopped walnuts or almonds.
Whip the egg whites to stiff peaks and fold them into the mixture.
Pour the batter into a greased cake pan and bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Whipped whites add air and lift, while the yolks add richness and structure.
- Vienna flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Castor sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Walnuts or almonds
- Add nutty flavour and a bit of body to the crumb.
- Baking powder
- Releases gas during baking so the cake rises and becomes lighter.
The step that matters
Folding in the whipped egg whites. Egg whites hold air only when whipped to stiff peaks. Folding gently keeps that air in the batter; stirring vigorously deflates it and leaves a dense cake.
Swap the walnut
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, vanilla):
- Almondfits better
- Chestnutfits better
- Macadamia nutfits better
- Walnutthe original
Fit is the average pairing score against flour, sugar, butter, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
