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
Prepare the fruit
Dredge the currants, raisins, and citron with a portion of the flour.
Make the batter
In a bowl, combine the bread crumbs, sour milk, remaining flour, suet, sugar, and dissolved baking soda; mix thoroughly.
Gently fold in the dredged fruit and chopped apples.
Steam and serve
Pour the mixture into a greased round tin basin and cover with an inverted plate or pie pan.
Place the basin in a steamer over boiling water and steam for 2.5 hours without lifting the lid.
Serve immediately with tart fruit or lemon sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk or buttermilk
- Provides acidity that reacts with the baking soda to lift the pudding.
- Baking soda
- Reacts with the sour milk to produce gas, helping the pudding rise and turn light.
- Beef suet
- Adds fat and richness, keeping the pudding moist and tender as it steams.
- Bread crumbs
- Absorbs liquid and gives the pudding a soft, tender crumb structure.
- White flour
- Provides the main structure that holds the pudding together as it steams.
- Currants, raisins, and citron
- Add chewy texture and concentrated fruit sweetness throughout the pudding.
The step that matters
Steam without lifting the lid. Lifting the cover lets steam escape and the temperature drop, which can stall the rise and leave the pudding dense and uneven.
Swap the currant
How well each one fits the dish's main ingredients (milk, flour, bread, beef, apple, raisin, sugar):
- Figfits better

- Currantthe original
Fit is the average pairing score against milk, flour, bread, beef, apple, raisin, sugar. Candidates are from the same food group and used in at least 100 recipes.
