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 ↓

Fruit Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Preheat the oven to 300°F (150°C).

  2. Beat the yolks of the eggs, butter, and brown sugar together until light.

  3. Whip the egg whites to a stiff froth and stir them in alternately with the flour.

  4. Add the spices, currants, and raisins to the mixture.

Layer and bake

  1. Layer the dough in a pan, followed by a layer of thinly sliced citron, and repeat until all ingredients are used.

  2. Bake for 4 hours.

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.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
Yolks enrich and bind the batter, while whipped whites lighten its structure.
Butter
Adds fat and richness, giving the cake a tender crumb.
Brown sugar
Adds sweetness and moisture, and helps the batter brown.
Flour
Provides the structure that holds the cake together as it bakes.
Raisins
Add chewy sweetness and moisture throughout the cake.
Currants
Add small bursts of sweetness and moisture throughout the cake.

The step that matters

Folding in the egg whites. Whipped whites hold air that lightens the batter. Stirring them in alternately with the flour, rather than beating hard, keeps that air from collapsing and keeps the batter light.

Swap the currant

How well each one fits the dish's main ingredients (egg, butter, sugar, flour, molasses, raisin, cinnamon):

  1. Vanillafits better
  2. Figfits better
  3. Datesfits better
  4. Currantthe original

Fit is the average pairing score against egg, butter, sugar, flour, molasses, raisin, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
