Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Sunshine Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks of four eggs until thick and light.
Gradually add 1½ cups powdered sugar and beat for ten minutes.
Gently fold in the whipped egg whites until very stiff.
Sift 1 cup flour with 1 teaspoon cream of tartar five times, then mix gently into the batter.
Add 1 teaspoon vanilla or the grated rind and 1 tablespoon lemon juice.
Bake
Turn the mixture into an ungreased mold.
Bake for 45 minutes in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a stiff foam, they trap air that lifts and structures the cake as it bakes.
- Egg yolks
- Beaten until thick, they add richness, moisture and a tender crumb.
- Flour
- Its proteins set during baking, giving the light cake its firm framework.
- Powdered sugar
- Adds sweetness and helps give the batter a fine, tender texture.
- Cream of tartar
- Acid that stabilises the whipped egg whites so their foam holds its shape.
- Lemon juice
- Adds acidity and bright lemon flavour to the batter.
The step that matters
Fold in the whipped egg whites gently. Whipped egg whites trap air that makes the cake rise. Folding gently keeps that air in; stirring hard deflates the foam and leaves a dense, flat cake.
