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.
Make the batter
Cream the butter in a bowl.
Gradually add the sugar, mixing well.
Incorporate the beaten egg yolks and cold water.
Sift together the cornstarch, flour, and baking powder, then add to the mixture.
Fold in the beaten egg whites gently.
Bake
Pour the batter into a pan, top with chopped almonds, and sprinkle with powdered sugar.
Bake for 40 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- Egg whites
- Beaten stiff and folded in, they trap air that lifts and lightens the cake.
- Egg yolks
- Add richness and structure, helping bind the batter as it sets.
- Cornstarch
- Lightens the crumb and gives the cake a fine, tender, velvety texture.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Flour
- Provides the main structure that sets the cake as it bakes.
The step that matters
Folding in the beaten egg whites. Stirring too vigorously deflates the air bubbles in the whites, which are needed to lift the batter. Fold gently with a wide motion so the cake rises and stays light.
