Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Plum Pudding
Ingredients
Directions
Prepare
Mix flour with baking powder and add salt, eggs, milk, and butter.
Roll the dough on a floured surface to about 1 inch thick.
Strain the plums through a colander and place them in the center of the dough, then fold the dough over to enclose the plums.
Steam and serve
Place the pudding in a mold and steam for 1½ hours.
Serve with hard sauce.
Serve with heated plum juice mixed with a little sugar and cinnamon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the dough structure that encloses the plums and holds the pudding together.
- Baking powder
- Releases gas during steaming, helping the pudding rise and become light.
- Eggs
- Add structure and richness, helping the dough set and bind.
- Butter
- Adds fat for tenderness and a richer flavour in the dough.
- Canned plums
- Provide sweet-tart fruit flavour and moisture inside the pudding.
The step that matters
Enclosing the plums in the dough. If the dough is rolled too thin or the plums are not fully sealed inside, juice can leak out during steaming and the pudding may become soggy or fall apart. Draining the plums well also limits excess liquid.
Swap the plum
How well each one fits the dish's main ingredients (butter, flour, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Plumthe original
Fit is the average pairing score against butter, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
