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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the butter and powdered sugar until smooth.
Add the egg whites and mix well.
Sift in the flour and baking powder, then fold gently.
Flavor the mixture with lemon.
Bake
Pour the batter into a greased cake pan and bake until golden.

Flour and butter 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
- Creams with the sugar to add richness and a tender crumb.
- Powdered sugar
- Sweetens the batter and helps create a fine, smooth texture when creamed.
- Egg whites
- Add structure and help the cake set as it bakes.
- Flour
- Provides the main structure that holds the cake together.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Fold in the flour and baking powder gently. Overmixing develops gluten in the flour, which toughens the cake and can deflate the air trapped in the creamed batter, leading to a dense crumb.
Swap the lemon

Fit is the average pairing score against sugar, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
