Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rolfe White 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).
Make the batter
Cream the butter and sugar together until light and fluffy.
Sift the flour twice, once with the baking powder.
Add the milk and flour alternately to the creamed mixture.
Gently fold in the beaten egg whites.
Add almond extract to taste.
Bake
Pour the batter into a greased cake pan and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten and folded in, they trap air and give the cake its light, airy structure.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
- Sugar
- Creamed with butter to aid aeration and adds sweetness and golden browning.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Milk
- Adds moisture and liquid that hydrates the flour to form the batter.
The step that matters
Folding in the egg whites. Beaten egg whites hold the air that lifts the cake. Stirring them vigorously or overmixing deflates the foam, leaving a dense, flat crumb, so fold gently until just combined.
