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 ↓
Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream together the butter and sugar.
Add the egg yolks gradually and stir well.
Mix in the grated chocolate and chopped almonds.
Fold in the flour, beaten egg whites, and baking powder.
Bake
Pour the batter into a prepared baking tin.
Bake in a 350°F (175°C) oven for 1½ hours.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 give the cake a tender, rich texture.
- Egg yolks
- Add richness and emulsify the batter, helping it bind smoothly.
- Egg whites
- Whipped and folded in, they trap air that lifts and structures the cake.
- Flour
- Provides the structure that holds the cake together as it sets.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Grated chocolate
- Adds deep flavour and moisture to the crumb.
The step that matters
Fold in the egg whites. Folding gently keeps the air trapped in the beaten whites. Stirring vigorously deflates the batter, so the cake bakes up dense instead of light.
