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 ↓
Prune Cake
Ingredients
Directions
Make the batter
Mix one and one-half cupfuls of sugar, one cupful of milk, one-half cupful of butter, three small teaspoonfuls of baking powder, whites of three eggs, and nearly three cupfuls of flour.
Bake the batter in two or three layers.
Make the filling
Steam the prunes so you can remove the pits.
Chop the prunes, raisins, and figs together.
Add the pulp and rind of a lemon to the chopped fruit.
Beat two tablespoonfuls of sugar with the yolks of three eggs.
Warm the mixture in a steamer until it sticks together.
Assemble
Spread the filling between the layers and frost the top.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites add structure to the batter, and yolks enrich the filling and add moisture.
- Flour
- Forms the structure of the cake layers as its proteins set during baking.
- Butter
- Adds fat for tenderness and richness in the cake layers.
- Baking powder
- Releases gas during baking so the layers rise.
- Prunes
- Provide moisture, sweetness and body to the filling.
The step that matters
Warm the fruit mixture in a steamer until it sticks together. Gentle heat softens the chopped fruit and lets its natural pectin and starches bind it into a spreadable filling. Heating too little leaves it loose, while overheating can make it dry or scorch.
Swap the fig
How well each one fits the dish's main ingredients (sugar, milk, butter, flour, raisin, egg):
- Vanillafits better
- Figthe original
- Coconutfits less well
- Lemonfits less well
Fit is the average pairing score against sugar, milk, butter, flour, raisin, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
