Why it works: Flour and nutmeg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 18,623 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Rock Cakes

Ingredients

Directions

Prepare the dough

  1. In a bowl, combine ½ pound of flour and 2 teaspoons of baking powder.

  2. Rub ¼ pound of clarified dripping into the flour until no lumps remain.

  3. Clean and pick over ¼ pound of currants to remove any stones, then add them to the flour.

  4. Stir in 1 teaspoon of ground ginger or grated nutmeg and ¼ pound of sugar.

  5. Chop 2 ounces of candied peel into pieces and add to the mixture.

  6. Mix all ingredients together with a wooden spoon.

  7. In a cup, beat 1 egg with ½ cup of milk, then pour into the mixture and stir until a stiff paste forms.

Shape and bake

  1. Grease a baking tin with dripping.

  2. Using two forks, divide the paste into small portions and place them in rough heaps on the tin.

  3. Bake in a preheated oven at 400°F (200°C) for about 15 minutes.

  4. Remove from the oven when done; the cakes are ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the structure that holds the cakes together as they bake.
Clarified dripping
Rubbed into the flour to add richness and a tender, crumbly texture.
Baking powder
Releases gas in the heat, helping the cakes rise and stay light.
Egg
Binds the mixture and adds moisture and structure to the paste.
Milk
Moistens the flour so the mixture forms a stiff, workable paste.
Sugar
Adds sweetness and helps the cakes brown lightly in the oven.

The step that matters

Stirring in the egg and milk to a stiff paste. Too much liquid makes the paste slack and the cakes spread instead of holding rough heaps. Stop stirring once the paste just comes together, so the baking powder's rise is not weakened by overworking.

Swap the currant

How well each one fits the dish's main ingredients (flour, sugar, nutmeg, egg, milk):

  1. Raisinfits better
  2. Vanillafits better

  4. Currantthe original

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