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
Pound the blanched almonds in a mortar until fine.
Make the batter
Mix the almond paste with the 3 egg whites, loaf sugar, grated lemon peel, and 15 egg yolks until well combined.
Gently fold in the beaten egg whites and sifted flour.
Prepare a mold and pour in the mixture.
Bake and cool
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
- Blanched almonds
- Ground almonds provide the bulk and nutty flavour of the cake in place of much flour.
- Egg yolks
- Yolks add richness, fat and colour, and help bind the batter.
- Egg whites
- Whipped whites trap air, giving the sponge its light, risen structure as it bakes.
- Loaf sugar
- Sugar sweetens the cake and helps keep the crumb tender and moist.
- Sifted dry flour
- A small amount of flour adds structure so the sponge holds its shape after baking.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air in the whipped whites. Stirring hard deflates the foam, so the sponge bakes up dense instead of light.
