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 ↓
Lyonnaise 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
Pound the almonds to a paste with the white of 1 egg.
Mix in the rum and sugar, then add the yolks of the eggs one at a time, beating well.
Gently fold in the sifted flour and the stiffly beaten whites of the 2 remaining eggs.
Butter a dome-shaped mold and pour in the batter.
Bake and fill
Bake in a moderate oven at 350°F (175°C) for 25 minutes.
Let cool, turn out of the mold, and cut crosswise into half-inch slices.
Spread a good custard filling over each slice and replace the slices as they were originally.
Decorate and serve
Decorate with whipped cream and serve with a claret sauce in a separate bowl.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Almonds
- Ground into a paste, they give the cake its dense, moist, nutty body.
- Eggs
- Yolks enrich and bind the batter, while whipped whites lighten it and help it rise.
- Flour
- Provides the starch structure that holds the cake together once baked.
- Sugar
- Adds sweetness and helps the batter stay tender and browned.
- Jamaica rum
- Adds aroma and flavor to the batter.
The step that matters
Folding in the whites. Stiffly beaten whites hold air that lightens the batter. Folding gently keeps that air in; stirring hard deflates it and leaves a dense, heavy cake.
