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 ↓
Denver Pound Cake
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).
Mix and bake
In a large bowl, break the eggs one at a time and beat them by hand.
Cream together the butter and powdered sugar.
Add the flour and lemon rind to the mixture and mix well.
Pour the batter into a prepared cake pan and bake for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming butter traps air and gives the cake its rich, tender crumb.
- Powdered sugar
- Sweetens the cake and dissolves finely, helping the batter stay smooth.
- Eggs
- Bind the batter and set in the oven, giving structure and some lift.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Lemon rind
- Adds fragrant citrus aroma from the oils in the peel.
The step that matters
Creaming the butter and powdered sugar. Beating butter with sugar traps tiny air bubbles that expand in the oven and lighten the crumb. Under-beating leaves a dense cake, while over-mixing after adding flour toughens it.
