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 the batter
Preheat the oven to 300°F (150°C).
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 mix well.
Fold in the beaten egg whites and flour gradually.
Add the fruit and bake
Roll the raisins, currants, and citron in a little flour.
Add the rolled fruit and spices to the batter and mix well.
Pour the batter into a greased cake pan.
Bake for 2 hours, covering the top with paper while baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, beaten and folded in, add lightness and structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acidic sour milk to produce gas that helps the cake rise.
- Sour milk
- Adds moisture and acidity, which activates the baking soda for rising.
- Raisins
- Add moisture, chewiness and sweetness scattered through the cake.
The step that matters
Folding in the beaten egg whites and flour gradually. Egg whites hold air that gives lift, and deflating them by overmixing or adding flour all at once makes a dense, heavy 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.
