Why it works: Milk and butter 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
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
In a bowl, combine sour milk, baking soda, salt, and butter or lard.
Add enough flour to form a dough slightly stiffer than biscuit dough.
Assemble the dumplings
Peel and core the apples, then roll out the dough.
Place an apple on the dough, fill the cavity with sugar, and encase the apple in the dough.
Press the edges tightly together and tie a cloth around each dumpling if desired.
Cook and serve
Bring a pot of salted water to a boil and add the dumplings.
Boil for 30 minutes, ensuring the water covers the dumplings.
For baking, place dumplings in a shallow pan, add hot water to cover the bottom, and bake in a preheated oven at 400°F (200°C) for 30 to 45 minutes.
Serve the dumplings on a platter with the cooking liquid in a sauceboat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas, helping the dough rise and turn tender.
- Baking soda
- Reacts with the acid in sour milk to release carbon dioxide, leavening the dough.
- Butter or lard
- Adds fat that makes the dough tender and flaky rather than tough.
- Flour
- Forms the gluten structure that gives the dough its body and holds the apple inside.
- Sugar
- Sweetens the apple filling and helps it caramelize slightly as it cooks.
The step that matters
Pressing the edges tightly together. If the seams are not sealed, the filling and juices can leak out during boiling or baking, leaving the apple dry and the dough soggy.
Swap the apple
How well each one fits the dish's main ingredients (milk, butter, flour, biscuit, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against milk, butter, flour, biscuit, sugar. Candidates are from the same food group and used in at least 100 recipes.
