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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
In a mixing bowl, combine the egg whites, ½ cup butter, and 1 cup cold water.
Add 1½ cups sugar, 3 cups flour, 2 teaspoons baking powder, and flavor to taste.
Stir and beat for five minutes, adding water as needed for proper consistency.
Bake
Pour the batter into a prepared baking pan and bake in a 400°F (200°C) oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that sets as the cake bakes.
- Egg whites
- Add structure and help trap air for a light crumb.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
- Butter
- Adds fat that tenderizes the crumb and gives richness.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
The step that matters
Beating the batter for five minutes. Beating traps air that helps the cake rise and gives a light texture. Gluten in the flour develops with mixing, so overbeating can make the crumb tough.
