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 ↓
French Almond Cake
Ingredients
Directions
The book says “a very quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Blanch the almonds by scalding them in hot water, then place them in cold water and dry them.
Pound the almonds one at a time in a mortar until smooth, adding a little water if needed to lighten them.
Separate the egg whites and yolks into two pans.
Make the batter
Beat the egg whites until stiff and the yolks until thick.
Gradually add the sugar to the yolks while beating hard, then mix in the almonds and essence of lemon.
Gently fold in the beaten egg whites, then slowly stir in the flour.
Butter a large cake pan and pour in the batter.
Bake and finish
Bake in a preheated oven at 400°F (200°C) for about an hour, or until done.
Once baked, cool the cake on a sieve.
Ice it and decorate with nonpareils.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by beating give the cake its light, airy structure, and yolks add richness.
- Almonds
- Ground almonds provide the bulk, moisture and nutty flavour of the cake.
- Powdered sugar
- Sweetens the batter and helps the yolks thicken into a smooth, stable base.
- Flour
- Adds a small amount of starch that gives the baked cake enough structure to hold its shape.
The step that matters
Folding in the beaten egg whites. Stiffly beaten whites hold the air that makes the cake rise. Folding gently keeps that air in, while vigorous stirring would deflate the batter and leave a dense cake.
