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 ↓
Plum Cake, Plain, for Family Use
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix flour and salt in a large bowl, making a hole in the center.
Pour yeast mixed with lukewarm water into the hole, stirring in enough flour to form a batter.
Cover with a cloth and let rise near a warm place for about 1 hour.
Once risen, melt butter (or lard/dripping) in hot milk and add cold milk to warm.
Add beaten eggs (if using), nutmeg or allspice, and brown sugar; knead well, adding more milk if necessary.
Cover again and let rise for another hour until very light.
Bake
Fold in raisins and currants.
Divide dough into six well‑greased tins and bake in a moderate oven (350°F/175°C) for about 1 hour or until a knife inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the dough that holds the cake together.
- German yeast
- Produces gas as it ferments, causing the dough to rise and become light.
- Butter, lard, or beef dripping
- Adds fat that tenderizes the crumb and enriches the dough.
- Hot milk
- Adds moisture and softness to the dough.
- Brown sugar
- Adds sweetness and moisture, and helps the crust brown.
- Raisins and currants
- Add sweetness and fruitiness, distributed through the crumb.
The step that matters
Second rise until very light. Yeast needs time to build gas and stretch the gluten network; under-proofed dough bakes dense, while the structure needs enough rise to hold the fruit and give a light crumb.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, milk, egg, nutmeg, sugar, raisin):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, butter, milk, egg, nutmeg, sugar, raisin. Candidates are from the same food group and used in at least 100 recipes.
