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 ↓
Plain Plum Pudding
Ingredients
Directions
Prepare the fruit
Finely mince the suet and mixed peel.
Wash and dry the currants, stone the raisins, and cut them in half.
Mix the batter
In a large bowl, mix the flour, breadcrumbs, brown sugar, and suet.
Add the currants, raisins, lemon zest, baking soda, salt, and mixed spice. Mix thoroughly.
Beat the eggs and add a little milk.
Stir the lemon juice and treacle into the dry mixture.
Combine with the egg and milk to form a soft paste, adding more milk if needed.
Steam and serve
Pour the mixture into a greased basin and steam or boil the pudding for 4 hours.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Flour
- Provides the main structure that holds the pudding together as it cooks.
- Suet
- Adds fat that keeps the pudding moist and rich as it steams.
- Breadcrumbs
- Absorb liquid and give the pudding a light, tender crumb.
- Eggs
- Bind the mixture and help it set firm during steaming.
- Baking soda
- Reacts with the acidic lemon juice and treacle to lighten the texture.
- Treacle
- Adds sweetness, dark colour and moisture to the pudding.
The step that matters
Steam the pudding for the full 4 hours. Steaming gently cooks the thick mixture through without drying it out. Letting the water boil dry or cutting the time short can leave the centre dense and underdone.
Swap the currant
How well each one fits the dish's main ingredients (flour, raisin, sugar, lemon, milk, egg):
- Vanillafits better
- Figfits better
- Orangefits better
- Currantthe original
Fit is the average pairing score against flour, raisin, sugar, lemon, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
