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 Apple Dumplings
Ingredients
Directions
Make the dough
Mix flour, lard, butter, baking soda dissolved in a little hot water, cream of tartar, and salt in a bowl.
Add enough milk to form a soft dough.
Roll out the dough to less than ½ inch thick and cut into squares.
Form the dumplings
Place an apple in the center of each square and bring the corners together.
Wrap each dumpling in a small, floured cloth and tie the top, leaving room for expansion.
Boil
Boil the dumplings for 50 minutes.

Flour and butter 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
- All-purpose flour
- Forms the gluten network that gives the dough its structure while it boils.
- Lard
- Adds fat that tenderises the dough and keeps it short.
- Butter
- Adds fat and flavour, making the dough richer and softer.
- Baking soda
- Reacts with the cream of tartar to produce gas that helps the dough rise.
- Cream of tartar
- Acidic partner to baking soda, producing gas for lift and balancing the dough.
- Apples
- Provide moisture and tartness that soften and flavour the dumpling as it cooks.
The step that matters
Leave room for expansion when wrapping. The dough rises as the baking soda and cream of tartar release gas during boiling. If the cloth is wrapped too tightly, the dumpling cannot expand and may split or turn dense.
Swap the apple
How well each one fits the dish's main ingredients (flour, butter, cream, milk):
- Vanillafits better
- Raisinfits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against flour, butter, cream, milk. Candidates are from the same food group and used in at least 100 recipes.
