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 ↓

Black 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Scorch the flour in the oven until it is a cinnamon color.

Make the batter

  1. In a large bowl, cream together the butter and sugar.

  2. Add the eggs one at a time, mixing well after each addition.

  3. Stir in the molasses, currants, raisins, citron, brandy, cloves, mace, cinnamon, and ginger.

  4. Gradually add the scorched flour, mixing until well combined.

Bake

  1. Pour the batter into a greased cake pan and bake for about 1.5 to 2 hours, or until a toothpick comes out clean.

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 crumb.
Eggs
Bind the batter and add structure as the cake sets in the oven.
Molasses
Adds moisture, deep sweetness and the dark color of the cake.
Flour
Forms the cake's structure once it is mixed into the batter and baked.
Currants
Add chewy pockets of fruit and moisture throughout the cake.
Raisins
Add chewy pockets of sweetness and moisture throughout the cake.

The step that matters

Scorching the flour. Heating flour in the oven browns it and develops nutty, toasted flavor and color. Watch it closely, because flour that goes past cinnamon color can turn bitter and burnt.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Currantthe original
  4. Applefits about as well

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