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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
Make the batter
Beat the egg whites until stiff peaks form.
In a separate bowl, mix the beaten egg yolks with the powdered sugar and beat thoroughly for 15 minutes.
Gradually add the flour, dredging it in a little at a time.
Gently fold in the beaten egg whites until well combined.
Shape and bake
Drop spoonfuls of batter onto a greased and floured baking tin, shaping them like half peaches.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites whipped to stiff peaks give the cakes lift and an airy, light structure.
- Egg yolks
- Yolks beaten with sugar add richness and help the batter set in the oven.
- Powdered sugar
- Sugar beaten with the yolks adds sweetness and helps create a fine, tender crumb.
- All-purpose flour
- Flour provides the structure that holds the cakes together as they set in the oven.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cakes their lift. Stirring or deflating them vigorously knocks out air, leaving dense, flat cakes.
