Why it works: Raisin and flour 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

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

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

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

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

  4. Stir in the brandy or whiskey.

  5. In another bowl, combine the flour, mixed spice (or cinnamon), baking soda, and nutmeg.

  6. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

  7. Fold in the raisins and currants.

Bake

  1. Pour the batter into a greased cake pan.

  2. Bake for 3 hours or until a toothpick inserted in the center comes out clean.

    Shared aroma: guaiacol (smoky, sweet).

Cinnamon and sugar 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
Creams with sugar to trap air and add richness and tenderness to the crumb.
Brown sugar
Creamed with butter for sweetness, moisture, and a deeper, caramel-like flavor.
Eggs
Bind the batter and add structure as the cake sets in the oven.
Flour
Forms the structure of the cake as its proteins set during baking.
Raisins
Add chewy texture, sweetness, and moisture to the finished cake.
Currants
Add chewy texture, tartness, and moisture throughout the cake.

The step that matters

Gradually add the dry ingredients to the wet mixture. Adding flour in stages and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough.

Swap the currant

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

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

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