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 ↓
Chocolate Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Beat the butter until creamy.
Make the batter
Add the egg yolks and grated chocolate, warmed in the oven, and mix well.
Incorporate the flour, sugar, and finely ground almonds.
Fold in the egg whites beaten to a froth and the salt.
Bake and finish
Pour the batter into a prepared pan and bake.
Ice with chocolate to keep it moist.
Let the cake rest for three days before serving.

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
- Eggs
- Egg yolks enrich the batter, and whipped whites add air that gives the cake structure.
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Sal volatile
- A leavening agent that releases gas during baking, helping the cake rise and lighten.
- Almonds
- Finely ground almonds add moisture, body and a nutty flavour to the crumb.
- Chocolate
- Adds richness, deep flavour and moisture to the batter and the icing.
The step that matters
Folding in the egg whites. Beaten egg whites hold air bubbles that help the cake rise. Folding gently rather than stirring keeps those bubbles intact, so the batter does not deflate before it reaches the oven.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
