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.
Make the dough
In a bowl, combine sour milk, baking soda, salt, and butter or lard.
Add enough flour to form a stiff dough.
Assemble the dumplings
Peel and core the apples.
Roll out the dough and place an apple on each piece.
Fill the cavity of each apple with sugar and encase it in the dough.
Press the edges together and tie a cloth around each dumpling if desired.
Cook and serve
Boil a kettle of slightly salted water and add the dumplings.
Ensure the water covers the dumplings and boil for 30 minutes.
For baking, place dumplings in a shallow pan, pour in hot water to cover the bottom, and bake at 400°F (200°C) for 30 to 45 minutes.
Serve the dumplings on a platter with the cooking liquid in a sauceboat.

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
- Sour milk
- Its acidity reacts with baking soda to produce gas, helping the dough rise lightly.
- Baking soda
- Reacts with the acid in sour milk to release carbon dioxide, leavening the dough.
- Butter or lard
- Adds fat that tenderizes the dough and gives it a rich texture.
- Flour
- Forms the gluten structure that holds the dough around the apple.
- Apples
- Provide moisture and tartness that contrast with the sweet filling and rich dough.
The step that matters
Encasing the apples in dough. The dough must be fully sealed around each apple, with edges pressed together, so that filling and juices stay inside during boiling or baking. Gaps let sugar and juices leak out and can make the dumpling soggy or cause it to break apart.
Swap the apple
How well each one fits the dish's main ingredients (milk, butter, flour, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against milk, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
