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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

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

Make the batter

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

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

  3. Stir in the molasses and sour milk.

  4. In a separate bowl, combine the flour, baking soda, and spices.

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

  6. Fold in the raisins, currants, and citron.

Bake

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

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.

    Shared aroma: isobutyraldehyde (malty, green).

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

Eggs
Bind the batter and add structure as the cake sets in the oven.
Butter
Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
Sugar
Sweetens the cake and helps create a soft, tender texture when creamed with butter.
Molasses
Adds moisture, deep sweetness and a dark color to the cake.
Baking soda
Reacts with the sour milk to produce gas that helps the cake rise.
Flour
Provides the structure that sets the cake's crumb as it bakes.

The step that matters

Gradually add the dry ingredients to the wet mixture, mixing until just combined.. Once flour meets liquid, gluten begins to form. Overmixing toughens the cake, so stop as soon as the batter is combined.

Swap the currant

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

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

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