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 ↓
Silver Cake
Ingredients
Directions
Prepare
Dredge the citron in 1 tablespoon of the weighed flour.
Set the flour and baking powder in a pan of hot water and stir occasionally.
In two bowls, place the egg whites with 1 tablespoon of sugar in each and beat to stiff foam.
Make the batter
Cream the butter and sugar together until light, then mix in half of the flour.
Add half of the beaten egg whites, then the remaining flour and egg whites.
Stir in the lemon extract, rose extract, and sherry wine, then fold in the citron.
Bake
Quickly pour the batter into a buttered cake pan and bake for 1 hour.

Butter and flour 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
- Egg whites
- Beaten to a stiff foam, they lighten the batter and give the cake its airy structure.
- Butter
- Creamed with sugar, it adds richness and a tender texture to the crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the heat of the oven, helping the cake rise.
- Sugar
- Sweetens the cake and helps the creamed butter become light and airy.
- Citron
- Dredged in flour so it stays suspended, adding bits of candied fruit flavor and chew.
The step that matters
Quickly pour the batter into the pan. Once the baking powder is mixed in and the egg whites are folded into the batter, its rising gas starts to escape and the foam begins to deflate. Delay lets the batter lose lift, so the cake may bake up dense.
