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, or Plum Cake
Ingredients
Directions
Prepare the fruit and spices
Pick the currants very clean, wash them, drain them through a colander, wipe them with a towel, spread them on a large dish, set them near the fire or in the hot sun to dry, placing the dish in a slanting position.
Having stoned the raisins, cut them in half, and when all are done, sprinkle them well with sifted flour to prevent sinking. When the currants are dry, sprinkle them also with flour.
Pound the spice, allowing twice as much cinnamon as mace. Sift it, and mix the mace, nutmeg, cinnamon together.
Mix also the liquor and rose-water in a tumbler or cup.
Cut the citron into slips.
Sift the flour into a broad dish.
Make the batter
Sift the sugar into a deep earthen pan, cut the butter into it, warm it near the fire if too cold, stir butter and sugar to a cream.
Beat the eggs as light as possible.
Stir eggs into butter and sugar alternately with the flour, stirring very hard.
Add gradually the spice and liquor.
Stir the raisins and currants alternately into the mixture, taking care that they are well floured.
Stir the whole as hard as possible for ten minutes after the ingredients are in.
Layer and bake
Cover the bottom and sides of a large tin or earthen pan with sheets of white paper well buttered, and put into it some of the mixture.
Spread on it some of the citron, which must not be cut too small.
Next put a layer of the mixture, then a layer of citron, and so on until it is all in, having a layer of the mixture at the top.
Bake the cake in a baker's oven for four or five hours, in proportion to its thickness.
After baking, let it stay in the oven all night or until it gets quite cold.
Ice it the next day.

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
- Eggs
- Beaten eggs trap air and bind the batter, giving the cake its structure.
- Butter
- Creamed with sugar, it adds richness and a tender crumb.
- Flour
- Provides the structure that holds the cake together once baked.
- Powdered white sugar
- Creamed with butter, it adds sweetness and helps give a light texture.
- Raisins
- Add sweetness, moisture and chewy body to the cake.
- Currants
- Add moisture, sweetness and chewy body throughout the cake.
The step that matters
Flouring the raisins and currants. Fruit tossed in flour is less likely to sink to the bottom of a heavy batter, so the fruit stays evenly distributed through the cake.
Swap the currant
