Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Nut Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the beaten yolks of the eggs and mix well.
Stir in the flour mixed with baking powder.
Fold in the stiffly beaten egg whites.
Add the chopped nuts, orange rind, and orange juice.
Bake
If baking as a solid cake, bake in a 300°F (150°C) oven for 2 hours on a small stand.
If baking in layers, bake in a 400°F (200°C) oven for 20 minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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
- Yolks add richness and moisture; whites, whipped stiff, lift and give the cake its structure.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Hickory nut kernels
- Add body, texture and nutty flavour to the crumb.
- Orange juice
- Adds moisture and bright acidity that balances the sweetness.
The step that matters
Folding in the stiffly beaten egg whites. Egg whites hold the air that makes the cake light. Folding gently, rather than stirring, keeps that air from collapsing, so the cake rises evenly in the oven.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
