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
In a large bowl, cream the butter and sugar together.
Add the chopped suet and mix well.
Stir in the flour, raisins, currants, and shredded citron.
In a separate bowl, combine the beaten egg whites and yolks, then add to the mixture.
Pour in the milk and brandy, mixing until combined.
Add the cloves, mace, and grated nutmeg, and stir thoroughly.
Steam and serve
Transfer the mixture to a pudding mold and steam for several hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add richness and structure as the pudding sets.
- Flour
- Provides the body and structure that holds the pudding together.
- Butter
- Adds fat and richness, creating a tender crumb with the sugar.
- Suet
- Adds fat that keeps the pudding moist and gives a rich texture.
- Sugar
- Adds sweetness and helps cream the butter for a lighter batter.
- Raisins
- Add sweetness, chewy texture and moisture to the pudding.
The step that matters
Steam and serve. Steaming gently over several hours sets the batter through without drying it. Keeping the water at a steady simmer and topping it up prevents the pudding from becoming heavy or undercooked in the center.

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.
