Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

White Sponge Cake

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 300°F (150°C).

  2. In a bowl, combine the powdered sugar, sifted flour, and cream of tartar.

  3. In a separate bowl, beat the egg whites until very stiff.

Make and bake the batter

  1. Gently fold the flour and sugar mixture into the beaten egg whites, being careful not to overmix.

  2. Pour the batter into a prepared cake pan and bake for about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Beaten until stiff, they trap air and give the cake its light, airy structure.
Cream of tartar
Stabilizes the beaten egg whites so their foam holds its shape longer.
Flour
Provides the structure that sets the cake as the egg foam bakes.
Powdered sugar
Sweetens the cake and dissolves easily into the egg whites for a fine crumb.

The step that matters

Folding the flour mixture into the egg whites. Overmixing knocks air out of the beaten whites, causing a dense, flat cake. Fold gently, just until the flour is no longer visible, so the foam keeps its volume through baking.
