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 ↓

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.
Prepare
Preheat the oven to 300°F (150°C).
Grease a cake mold and dust it with flour, removing any excess.
Line the bottom with parchment paper and grease it.
Make the batter
Cream the butter and powdered sugar together until light and fluffy.
Add the flavoring and mix well.
Beat the egg whites until very stiff peaks form.
Gradually fold the egg whites into the butter mixture, mixing lightly.
Sift the flour and baking powder together five times, then gently fold into the batter.
Bake
Pour the batter into the prepared mold and bake for about 2 hours.

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 add richness and a tender crumb.
- Egg whites
- Whipped to stiff peaks to give the cake its lift and light, airy structure.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking so the cake rises.
- Powdered sugar
- Sweetens the batter and helps create a fine, tender texture when creamed with butter.
The step that matters
Folding the egg whites into the batter. Whipped egg whites hold the air that lifts the cake. Overmixing or deflating them with vigorous stirring loses that air, leaving a dense, heavy cake. Fold gently and keep the mixture light.
