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 ↓
Christmas Plum Pudding
Ingredients
Directions
Make the batter
Cream the butter and sugar together.
Beat in the yolks of the eggs until smooth and light.
Add the milk, then the flour alternately with the beaten egg whites.
Stir in the brandy and spices, then fold in the dredged fruit. Mix all thoroughly.
Prepare the cloth and boil
Wring out a pudding cloth in hot water and flour it well inside.
Pour in the mixture and boil for five hours.

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
- Yolks enrich and bind the batter, while separately beaten whites lighten its structure.
- Flour
- Forms the body of the pudding, setting into a firm crumb as it cooks.
- Butter
- Creaming with sugar traps air and adds richness and a tender texture.
- Suet
- Its fat solidifies as the pudding cools, giving a rich, moist, crumbly texture.
- Sugar
- Creamed with butter, it adds sweetness and helps create a light batter.
- Raisins
- Dried fruit that adds sweetness, chew and moisture throughout the pudding.
The step that matters
Boiling the pudding for five hours. The pudding must be kept at a steady boil for the full time, because the batter cooks slowly through its dense fruit and fat. Too little heat or time leaves it heavy and underset in the centre.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, egg, milk, brandy):
- Vanillafits better
- Figfits better
- Apricotfits about as well
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, raisin, egg, milk, brandy. Candidates are from the same food group and used in at least 100 recipes.
