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 ↓

Ingredients

Directions

The book says “a quick 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. In a large bowl, mix the sugar and molasses until well combined.

  3. Add the butter and mix until smooth.

  4. Beat in the eggs one at a time, then stir in the brandy.

  5. Dissolve the baking soda in a small amount of water and add it to the mixture.

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

  7. Add spices to taste.

  8. Gradually add flour until the batter is thick enough to hold a spoon upright.

Bake

  1. Pour the batter into a greased cake pan.

  2. Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

    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 they set during baking.
Flour
Provides the structure that holds the dense batter together as it bakes.
Baking soda
Reacts with the molasses acidity to help the cake rise and lighten.
Molasses
Adds sweetness, dark color, and moisture to the cake.
Butter
Adds richness and tenderness through fat in the batter.
Raisins
Add chewy texture and concentrated fruit sweetness throughout the cake.

The step that matters

Gradually add flour until the batter is thick enough to hold a spoon upright. Adding flour too quickly or too little changes the batter's consistency, affecting structure and how evenly the dense fruit cake bakes through.

Swap the currant

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

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

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