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 ↓
Easily Made Fruit Cake
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
Preheat the oven to 300°F (150°C).
Make the batter
Cream together the sugar and butter.
Beat the egg yolks and mix them with the creamed mixture.
Add the sour milk and baking soda, then gradually mix in the flour.
Fold in the beaten egg whites last.
Roll the raisins, currants, and citron in a little flour.
Add the rolled fruit and spices to the batter and mix well.
Bake
Pour the batter into a greased pan and cover the top with paper.
Bake for 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the batter, while whipped whites lighten its structure.
- Baking soda
- Reacts with the sour milk to produce gas that helps the cake rise.
- Flour
- Its proteins set during baking to form the cake's structure.
- Butter
- Creaming with sugar traps air and adds richness and tenderness.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Sour milk
- Its acidity activates the baking soda and adds moisture.
The step that matters
Fold in the beaten egg whites last. Folding gently keeps the air whipped into the egg whites, which helps the cake rise and stay light. Stirring vigorously would deflate them and produce a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, milk, egg, raisin, cinnamon):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, milk, egg, raisin, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
