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
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.
Make the batter
Cream the butter and sugar together.
Add the spices.
Mix in the flour alternately with the well-beaten eggs.
Add the prepared fruit. Beat well.
Add the baking powder.
Bake
Bake in a moderate oven at 350°F (175°C) for 3 to 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cake together as it bakes.
- Butter
- Adds richness and tenderness, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a fine, tender crumb when creamed with butter.
- Eggs
- Bind the batter and add structure, moisture and richness.
- Baking powder
- Releases gas during baking so the cake rises and lightens.
- Raisins
- Add sweetness, chew and moisture to the cake.
The step that matters
Bake low and slow. A long, moderate bake lets the heat reach the dense center without the outside burning. Because the batter is heavy with fruit and nuts, underbaking leaves it gummy inside, while a hot oven would scorch the exterior before the middle sets.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, raisin, almond, orange):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg, raisin, almond, orange. Candidates are from the same food group and used in at least 100 recipes.
