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, butter, lard, and enough flour to make a very stiff dough.
Roll out the dough and cut it into circles large enough to encase the apples.
Fill and wrap the apples
Peel and core the apples, then fill each cavity with sugar.
Place each apple on a circle of dough and press the edges together to seal.
Cook and serve
Bring a kettle of slightly salted water to a boil and add the dumplings.
Boil the dumplings for 30 minutes, ensuring they are covered by water.
Alternatively, steam the dumplings or bake them in a soft dough or baking powder crust.
For baking, place in a shallow pan, bake at 400°F (200°C) for 30 to 40 minutes, and serve with cream and sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Acidity reacts with baking soda to produce gas, helping the dough rise and stay tender.
- Baking soda
- Reacts with the acid in sour milk to release carbon dioxide, lightening the dough.
- Butter
- Adds fat that enriches flavour and makes the dough tender.
- Lard
- Adds fat that keeps the dough short and tender.
- Flour
- Provides structure, forming the gluten network that holds the dough around the apples.
The step that matters
Sealing the dough around the apples. Edges pressed together tightly keep the filling and sugar inside while cooking, so the dough does not split open in boiling water or hot steam.
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.
