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 ↓
Apple Pot Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Sift flour with baking powder and salt.
Rub in cold butter, then add milk to form a dough like tea biscuits.
Assemble and cook
Line a shallow stewpan with the dough, leaving 2 inches from the bottom.
Pour in water, apples, and sugar.
Wet the edges and cover with remaining dough.
Cover the stewpan and boil for 20 minutes.
Transfer to a 350°F (175°C) oven until apples are cooked.
Finish and serve
Remove from oven, cut the top crust into four equal parts.
Dish the apples and place pieces of side crust cut into diamonds and top crust on a plate.
Serve with cream.

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
- Flour
- Forms the dough's structure so the crust holds its shape around the apples.
- Butter
- Rubbed into the flour to make the crust tender and flaky.
- Royal baking powder
- Releases gas in the dough, helping it rise and lighten as it bakes.
- Apples
- Provide the main filling, softening as they cook through.
- Sugar
- Sweetens the apples and adds to the filling's flavour.
- Milk
- Hydrates the flour to bind the dough together.
The step that matters
Wet the edges and cover with remaining dough. Dampening the edges helps the top and bottom crusts seal, so the filling's juices don't leak out during cooking.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
