Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Gradually add sugar to melted butter.
Add the well-beaten yolk and then the milk.
Sift flour and baking powder together; shake some onto the raisins and nuts.
Slowly add flour to the mixture and beat until smooth.
Fold in melted chocolate, nuts, and raisins.
Gently cut in the stiff egg whites.
Bake
Drop by teaspoon onto a greased pan, 1 inch apart.
Bake in a moderate oven (350°F / 175°C) until firm to the touch.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter 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
- Egg
- The yolk enriches and binds the batter, while the whipped whites lighten its texture.
- Pastry flour
- Provides the structure that sets the cake as it bakes.
- Butter
- Adds richness and tender moisture to the crumb.
- Baking powder
- Releases gas that makes the drops rise and turn light.
- Melted chocolate
- Adds deep chocolate flavor and moisture throughout the cake.
- Sugar
- Sweetens the batter and helps give the cake a tender crumb.
The step that matters
Gently cut in the stiff egg whites. Stiff egg whites hold air that gives the cake its lift. Vigorous stirring deflates them, leaving a dense, flat result, so fold gently until just combined.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, egg, milk, flour, raisin, chocolate, butter):
- Almondfits better
- Chestnutfits better
- Pistachiofits about as well
- Nutsthe original
Fit is the average pairing score against sugar, egg, milk, flour, raisin, chocolate, butter. Candidates are from the same food group and used in at least 100 recipes.
