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 ↓

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.
Prepare
Preheat the oven to 350 °F (175 °C).
Grease small molds and fill them with the dough.
Make the dough
Crack 12 eggs into a large bowl and beat until mixed.
Gradually add 1 ¼ cups sugar and beat until dissolved.
Add 1 ¾ cups flour and mix into a light dough.
Bake and serve
Dust the tops with caster sugar and sprinkle with chopped almonds.
Bake in the oven until golden.
Let cool before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked eggs trap air and provide the structure that makes the sponge light.
- Caster sugar
- Sugar dissolved into the eggs sweetens the batter and helps it hold its airy texture.
- Fine pastry flour
- Flour gives the batter body and sets into the crumb as it bakes.
- Chopped blanched almonds
- Almonds add flavour and a toasty, golden surface when baked.
The step that matters
Beating the eggs and sugar. Eggs must be beaten until the sugar fully dissolves so the batter traps air. Under-beaten batter bakes dense, while over-mixing after adding flour knocks out that air and toughens the crumb.
