Why it works: Almond and flour 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 ↓
Almond Sponge Cake
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.
Prepare the batter
Pound the almonds in a mortar until fine.
Mix in the egg whites, sifted sugar, lemon peel, and egg yolks until well combined.
Beat the 12 egg whites to a solid froth and gently fold into the mixture.
Add the sifted flour and mix until just combined.
Bake and cool
Prepare a mold and pour in the mixture.
Bake in a slow oven at 300°F (150°C) for 1 hour.
Carefully remove from the mold and place on a sieve to cool.

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 froth, they trap air that lifts the cake and gives it a light, airy crumb.
- Egg yolks
- Add richness and moisture, and help bind the batter into a tender crumb.
- Blanched almonds
- Ground to form the bulk of the cake, giving it a moist, tender texture and nutty flavor.
- Sifted loaf sugar
- Sweetens the cake and helps stabilize the whipped egg whites while contributing to browning.
- Sifted dry flour
- Provides a small amount of structure so the cake holds its shape after baking.
The step that matters
Folding in the whipped egg whites. Whites must be beaten to a solid froth and folded in gently. Overmixing deflates the air bubbles that give the sponge its rise, leaving a dense cake.
