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

Prepare the batter

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

  2. Cream the butter and sugar together.

  3. Add the egg yolks and brandy, mixing well.

  4. Sift in the flour, then add the molasses, fruit, and spices.

  5. Dissolve the baking soda in a little water and add it along with the egg whites (do not beat them too stiff).

Bake

  1. Pour the batter into a prepared cake pan.

  2. Bake for 3 to 4 hours.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
Creamed with sugar to trap air and give the cake a tender, rich crumb.
Eggs
Egg yolks enrich and bind the batter, while whites add lift and structure.
Flour
Forms the structure that holds the heavy fruit and spices together as the cake sets.
Molasses
Adds moisture, deep sweetness, and color that browns the cake as it bakes.
Baking soda
Reacts with the molasses' acidity to release gas, helping the cake rise.
Raisins
Add chewy moisture and sweetness throughout the cake.

The step that matters

Egg whites folded in gently. Beating the whites too stiff can over-aerate the batter, causing collapse or a dense texture; gentle incorporation keeps the rise even and controlled.

Swap the currant

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

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

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