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 ↓
Irish Potato Dumpling
Ingredients
Directions
Prepare the dough
Pass the mashed potatoes through a sieve to remove lumps.
Mix in the lard and butter, then add the salt.
Sift the baking powder into ½ cup of flour and combine with the potato mixture.
Add milk gradually to form a stiff dough, incorporating more flour as needed.
Boil and serve
Roll the dough with any kind of fruit, then place it in a floured cloth and tie it securely.
Boil in a pot of water for two hours, ensuring the pot remains filled with boiling water.
Serve with a hot or cold sauce.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Mashed potatoes
- Provide the bulk and starchy body that gives the dumpling its soft, tender texture.
- Baking powder
- Releases gas during cooking to lighten the dough and help it rise.
- Lard
- Adds fat that tenderises the dough and keeps it from becoming tough.
- Butter
- Adds fat and flavour, enriching the dough's taste and mouthfeel.
- Flour
- Gives the dough structure so it holds together stiffly during boiling.
The step that matters
Keeping the pot filled with boiling water. Water that drops below a rolling boil cools the dumpling, slowing cooking and making the dough heavy and uneven. Topping up with boiling water keeps heat steady for the full two hours.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk):
- Potatothe original
- Arrowrootfits about as well
- Leekfits less well
- Shallotfits less well
Fit is the average pairing score against butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
