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 ↓

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 the batter

  1. Cream the butter and sugar together with a wooden spoon.

  2. Add the sultanas and half of the chopped almonds to the mixture.

  3. Mix the two flours together, ensuring there are no lumps.

  4. Break one egg at a time into the sugar mixture, adding a handful of flour with each egg, and beat well.

  5. Continue beating until all the eggs and flour are incorporated.

Bake

  1. Pour the mixture into a well-buttered cake tin lined with buttered paper.

  2. Decorate the top with the remaining almonds and bake for 1.5 hours in a moderate oven at 350°F (175°C).

Flour and butter 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, giving the cake a tender, rich crumb.
Eggs
Bind the batter and add structure as they set in the oven.
All-purpose flour
Provides the main structure of the cake as the batter sets.
Castor sugar
Creams with butter to aerate the batter and adds sweetness and browning.
Sultanas
Add moisture and chewy sweetness throughout the cake.

The step that matters

Adding the eggs to the creamed mixture. Eggs added too quickly can curdle the creamed butter and sugar, causing the batter to separate and lose air. Adding one egg at a time with a spoonful of flour, and beating well between additions, keeps the emulsion stable so the cake rises evenly.
