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 ↓
Boiled Potato Pudding
Ingredients
Directions
Prepare the batter
Boil the potatoes and mash them very fine.
While warm, add the butter and milk.
Beat the eggs until light and pour them into the mixture.
Add enough flour to make a very stiff batter.
Boil and serve
Flour the inside of a pudding bag and pour in the batter, which should be as stiff as soft dough.
Tie the bag tightly, leaving 2-3 inches at the top for the pudding to swell.
Boil for 2 hours.
Dip the bag briefly in cold water, then turn out the pudding.
Serve with your preferred sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the pudding its body after mashing.
- Butter
- Adds richness and fat, contributing softness and flavour to the pudding.
- Milk
- Adds moisture and helps the mashed mixture become a smooth, pourable batter.
- Eggs
- Bind the mixture and set during boiling to give the pudding structure.
- Flour
- Thickens the batter so it holds its shape as a stiff dough.
The step that matters
Tie the bag tightly, leaving room at the top. The pudding swells as it cooks, so a tight seal keeps water out and the batter together, while the open space at the top gives room to expand without bursting the bag.

Fit is the average pairing score against butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
