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, mix sour milk, baking soda, salt, and butter.
Add flour until the dough is 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 it in the dough.
Press the edges tightly together and tie a cloth around each dumpling if desired.
Cook and serve
Boil in a kettle of lightly salted water 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 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 that lightens the dough.
- Baking soda
- Reacts with the acidic sour milk to produce carbon dioxide, helping the dough rise.
- Butter
- Adds fat that tenderises the dough and contributes richness and flavour.
- Flour
- Provides the structure that holds the dough around the apples during cooking.
- Sugar
- Sweetens the apple filling and helps the fruit caramelise slightly as it cooks.
The step that matters
Pressing the dough edges tightly together. Sealed edges keep the filling in and stop water from entering during boiling or baking, so the apples stay moist and the dough does not fall apart.
Swap the apple
How well each one fits the dish's main ingredients (milk, butter, flour, sugar, cream):
- Vanillafits better
- Raisinfits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against milk, butter, flour, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
