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 ↓
Baked Plum Pudding
Ingredients
Directions
Prepare
Chop the suet finely, sprinkling a little flour to prevent sticking.
In a bowl, mix the flour and baking powder.
Add the chopped suet and rub it into the flour with your hands.
Pit the raisins and add them to the mixture.
Wash and dry the currants, then add them to the bowl.
Chop the candied peel and mix it in.
Add the sugar and sprinkle in the mixed spice.
Make the batter
Beat the egg and mix it with the milk.
Pour the egg and milk mixture into the bowl and stir until combined.
If needed, add more milk to achieve a stiff paste.

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
- Suet
- Rubbed into the flour, it adds richness and a tender, crumbly texture.
- All-purpose flour
- Provides the structure that holds the pudding together as it sets.
- Egg
- Binds the mixture and helps it set firm as it cooks.
- Baking powder
- Releases gas as it heats, helping the pudding rise and become light.
- Raisins
- Add sweetness and chewy moisture throughout the pudding.
- Milk
- Adds moisture to bring the dry ingredients into a stiff paste.
The step that matters
Adding the milk. Too much liquid makes the paste slack and the pudding heavy, while too little leaves dry flour unhydrated. Add milk gradually and stop once the mixture holds a stiff paste.
Swap the currant
How well each one fits the dish's main ingredients (flour, raisin, sugar, egg, milk):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, raisin, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
