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 ↓

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
Preheat the oven to 350°F (175°C).
Line a cake tin with buttered paper, including the bottom.
Make the batter
Beat the butter to a cream using a wooden fork.
Add the sugar and well-beaten eggs to the butter.
Mix the baking powder with the flour and gradually add it to the mixture.
Stir in the candied peel, stoned and chopped raisins, currants, and almonds. Beat the mixture well together.
Bake
Pour the mixture into the prepared tin.
Bake for about 1 hour.

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 and richness as they set in the oven.
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Flour
- Forms the main structure of the cake as the batter sets during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn lighter.
- Sugar
- Sweetens the cake and, creamed with butter, helps give a soft crumb.
The step that matters
Beating the butter to a cream. Creaming softened butter until light traps air that helps leaven the cake. If the butter is too cold or under-beaten, the batter stays dense and the crumb turns heavy.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, raisin, almond):

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