Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Apple Dumpling
Ingredients
Directions
Make the dough
Mash the hot potatoes in a bowl.
Add flour and salt to the mashed potatoes and mix thoroughly.
Cut the butter into the mixture until it resembles a paste.
Add cold water gradually to form a dough.
Flour a board and roll out the dough, thick in the middle and thin at the edges.
Wrap and boil
Place the quartered apples in the center of the dough.
Gather the edges of the dough over the apples and tie securely in a cloth.
Boil the dumpling in water for three hours.
Serve
Turn out onto a dish and serve with butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed starch that gives the dough a soft, tender body while it is still hot.
- Flour
- Forms the dough's structure, setting firm around the apples as it boils.
- Butter
- Cut into the flour mixture to add fat, tenderising the dough and making it short.
- Apples
- Filling that softens during boiling and becomes moist and sweet inside the dough.
The step that matters
Tie the cloth securely. If the seams or cloth are loose, water seeps into the dough during the long boil, making the dumpling soggy and letting the filling leak out.
Swap the apple
How well each one fits the dish's main ingredients (potato, flour, butter):
- Raisinfits better
- Coconutfits better
- Avocadofits better
- Applethe original
Fit is the average pairing score against potato, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
