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

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

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

  2. Cream the butter and powdered sugar together until light and fluffy.

  3. Gradually add the flour, mixing well.

  4. Fold in the raisins, currants, citron, and spices.

  5. Finally, stir in the whisky and molasses.

Bake

  1. Pour the batter into a prepared cake pan.

  2. Bake for 4 hours.

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

Butter
Creamed with sugar to trap air, giving the cake a light, tender crumb.
Flour
Forms the structure that holds the dense fruit and batter together as it bakes.
Molasses
Adds moisture, dark color and a deep sweetness to the cake.
Raisins
Add chewy texture and natural sweetness throughout the cake.
Currants
Add chewy texture and tart, concentrated fruit flavor throughout the cake.

The step that matters

Baking for 4 hours at 300°F. A dense, fruit-heavy batter needs a long, low bake so the center sets fully without the outside over-browning or drying. Checking doneness with a skewer before removing it helps prevent a gummy middle.

Swap the currant

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

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

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