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 ↓

The Pkeident's Christmas Cake

Oven, in the book's wordsA slow oven

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

  1. Soak the almonds in rose water overnight and the fruit in grape juice for the same time.

  2. Cream the butter and sugar together thoroughly.

Make the batter

  1. Add the well-beaten yolks of the eggs, then mix in the spices, grape jelly, and melted chocolate.

  2. Fold in the beaten egg whites and part of the flour.

  3. Roll the soaked fruit in the remaining flour and mix it into the batter in small quantities.

  4. Add the nuts last.

Bake or steam

  1. Bake or steam the cake for 4 to 6 hours in small or large molds.

  2. If steamed, dry it off in a slow oven at 300°F (150°C) for 1 hour.

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 give the cake a tender, rich crumb.
Sugar
Creams with butter for structure and adds sweetness and browning.
Browned and sifted flour
Provides the main structure that holds the heavy fruit and nuts together.
Eggs
Yolks enrich and bind the batter, while beaten whites add lightness and help it rise.
Seeded raisins
Add moisture, chewiness and sweetness throughout the cake.
Blanched almonds
Add richness, texture and a nutty flavour to the batter.

The step that matters

Rolling the soaked fruit in flour before mixing. Flour coats the wet, sticky fruit so it stays suspended in the batter instead of sinking to the bottom during baking.

Swap the grape

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