Why it works: Raisin and flour 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 Pudding
Ingredients
Directions
Prepare
Grease pudding basins or molds. Sprinkle with caster sugar if desired.
Prepare pudding cloths, strings, and pieces of greased white paper.
Stone the raisins. Wash and dry the currants. Clean the sultanas. Cut the peel into shreds. Blanch and shred the almonds. Make the bread crumbs. Chop the suet finely.
Make the batter
Break the eggs one at a time into a cup. Add them to a basin and beat well, adding a little milk.
In a separate basin, mix the flour with salt, spice, bread crumbs, and lemon rind. Add the suet, sugar, almonds, and fruit to the flour mixture.
Incorporate the eggs to form a loose paste.
Fill the basins to the top. Cover with paper, then with cloth.
Boil and serve
Place the puddings in boiling water. Boil for 6 to 10 hours, depending on size.
Remove the cloth and paper. Turn the pudding onto a hot dish. Sprinkle with caster sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and give the pudding its set structure as they cook.
- Suet
- Adds fat that keeps the pudding moist and rich during long steaming.
- Flour
- Provides the starch structure that holds the pudding together.
- Bread crumbs
- Absorb liquid and lighten the texture of the dense pudding.
- Sugar
- Adds sweetness and helps moisten and flavour the pudding.
- Raisins
- Add concentrated sweetness and chewy texture throughout the pudding.
The step that matters
Boil for the full time in boiling water. Long, steady steaming cooks the eggs and starch through and sets the dense mixture. Water that stops boiling or runs low lengthens cooking and can leave the pudding heavy or undercooked.
Swap the almond
The recipe marks almond as optional. How well each one fits the dish's main ingredients (raisin, currant, sugar, flour, bread, beef, egg):
- Almondthe original
- Chestnutfits about as well
- Pistachiofits less well
- Beansfits less well
Fit is the average pairing score against raisin, currant, sugar, flour, bread, beef, egg. Candidates are from the same food group and used in at least 100 recipes.
