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 ↓
Angel Cake
Ingredients
Directions
Prepare the batter
Sift the sugar and flour together once, then sift them together 5 more times.
Add salt to the egg whites and beat until light.
Sift in the cream of tartar and continue beating until very stiff and dry.
Carefully cut and fold the egg whites into the flour and sugar mixture, then add the almond flavoring.
Bake
Line an angel cake tin with oiled paper, pour in the batter, and place it in a cool oven.
After 25 minutes, increase the oven temperature and bake for an additional 25 minutes.
Avoid jarring the cake while it bakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps keep the whipped egg white foam stable.
- Flour
- Provides the starch that sets during baking to give the cake its crumb.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds its volume.
The step that matters
Folding the egg whites into the flour and sugar mixture. Overmixing or deflating the whipped egg whites knocks out the air that makes the cake rise. Gentle cutting and folding keeps the foam intact so the batter bakes up light.
