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 ↓
Scotch Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Mince enough ripe apples to fill a deep dish.
In a bowl, mix sweet milk, baking powder, and enough flour to create a stiff batter. Stir in melted butter.
Bake and serve
Spread the batter over the apples with a knife.
Bake until cooked through.
Turn the pie onto a plate, keeping the apples on top.
Season with sugar and butter to taste.

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
- Apples
- Form the filling, adding moisture and fruity flavor as they cook.
- Flour
- Gives the batter enough body to set into a firm layer over the fruit.
- Baking powder
- Releases gas that lifts the batter so it bakes lighter rather than dense.
- Sweet milk
- Hydrates the flour and keeps the batter moist and tender as it bakes.
- Butter
- Adds fat for richness and a softer, more tender crumb.
- Sugar
- Adds sweetness to the finished pie, balancing the tart apples.
The step that matters
Spread the batter over the apples. The batter must be stiff so it stays as a distinct layer on top instead of sinking into the wet fruit. Baking then sets it while the apples soften beneath.
Swap the apple
How well each one fits the dish's main ingredients (milk, flour, butter, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against milk, flour, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
