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 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

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

  2. Cream the butter and sugar together until smooth.

  3. In a separate bowl, combine the flour, baking powder, mixed spice, and nuts.

Make the batter

  1. Gradually add the dry ingredients to the creamed mixture, alternating with the eggs.

  2. Fold in the raisins, currants, and citron or mixed peel.

Bake

  1. Pour the batter into a prepared cake pan lined with paper on the bottom and top.

  2. Bake for three hours.

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.

    Cooked together124,287 recipes

    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

Butter
Creams with sugar to trap air, giving the cake a tender, rich crumb.
Flour
Forms the main structure that holds the cake together as it sets.
Eggs
Bind the batter and add structure and richness as they set in the oven.
Baking powder
Releases gas in the heat, helping the cake rise and lighten.
Golden sugar
Sweetens the cake and helps create a soft texture when creamed with butter.
Raisins
Add moisture and concentrated sweetness throughout the fruit cake.

The step that matters

Folding in the fruit. Heavy fruit can sink to the bottom if the batter is too thin or the fruit is overmixed. Gentle folding keeps the fruit evenly distributed while preserving the air trapped in the batter.

Swap the nuts

The recipe marks nuts as optional. How well each one fits the dish's main ingredients (butter, flour, sugar, raisin, currant, syrup, egg):

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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