Why it works: Flour and butter 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 ↓

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.
Make the batter
Cream the sugar and butter together.
Add the water and flour, and mix well.
Stir in the chopped walnuts.
Gently fold in the egg whites mixed with baking powder.
Bake
Pour the mixture into square pans.
Bake for about 35 minutes in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped or folded in to trap air, helping the cake rise and turn light.
- Baking powder
- Releases gas in the batter, causing the cake to rise in the oven.
- Flour
- Forms the gluten and starch structure that sets the cake's crumb.
- Butter
- Adds fat for tenderness and flavor, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Walnuts
- Add crunch and a nutty flavor that contrasts with the soft crumb.
The step that matters
Gently fold in the egg whites mixed with baking powder. Folding rather than stirring keeps the air bubbles in the egg whites intact. Those bubbles and the gas from baking powder are what lift the cake, so overmixing deflates it.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, egg, flour, meat, butter):
- Almondfits better
- Walnutthe original
- Chestnutfits about as well
- Pecansfits about as well
Fit is the average pairing score against sugar, egg, flour, meat, butter. Candidates are from the same food group and used in at least 100 recipes.
