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).
Beat the eggs separately.
Cream the butter and sugar together.
Mix the sifted flour and spices.
Make and bake the cake
Combine all ingredients and mix well.
Pour the batter into a greased cake pan.
Bake in the preheated oven until a toothpick comes out clean.

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
- Creamed with sugar to trap air and add tenderness and richness.
- Sugar
- Creamed with butter and adds sweetness and helps the cake brown.
- Flour
- Forms the structure of the cake as it sets during baking.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
- Figs
- Add moisture and concentrated sweetness throughout the cake.
The step that matters
Bake until a toothpick comes out clean. Fruit-heavy batter is dense and holds moisture, so underbaking leaves a wet, gummy center while overbaking dries the crumb. A toothpick test shows when the centre has set.
Swap the ginger
How well each one fits the dish's main ingredients (flour, sugar, butter, raisin, fig, almond, egg):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Gingerthe original
Fit is the average pairing score against flour, sugar, butter, raisin, fig, almond, egg. Candidates are from the same food group and used in at least 100 recipes.
