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 ↓

Jelly Fruit Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

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

  2. Cream together the sugar and butter.

  3. Add the sweet milk, flour, eggs, and baking powder; mix well.

  4. Divide the batter in half and bake one half in two pans.

  5. To the remaining batter, add molasses, raisins, currants, and chopped citron; mix well.

  6. Bake the second half in two tins.

Assemble

  1. Once baked, layer the four cake layers alternately with frosting and jelly.

The flavor team

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.

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
Adds fat that makes the cake tender and rich in texture.
Eggs
Provide structure and help bind the batter as it sets in the oven.
Flour
Forms the main structure of the cake as its proteins set during baking.
Baking powder
Releases gas during baking so the layers rise and become light.
Molasses
Adds moisture, dark colour and a deeper sweetness to the darker batter.

The step that matters

Dividing the batter in half. The two halves are baked separately, so the batter should be split evenly to give layers of matching thickness and bake time.

Swap the currant

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

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

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