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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Mince enough ripe apples to fill a deep dish.
Make the batter and assemble
In a bowl, mix sweet milk, melted butter, baking powder, and flour to make a stiff batter.
Spread the batter over the apples with a knife.
Bake and serve
Bake for about 30-40 minutes or until golden brown.
Turn the pie upside down on a plate and season with butter and sugar.

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
- Ripe apples
- Forms the fruit filling that softens and cooks beneath the batter.
- Sweet milk
- Hydrates the flour so it forms a batter that bakes into a set crust.
- Melted butter
- Adds fat that enriches the batter and keeps it tender.
- Baking powder
- Releases gas during baking, helping the batter rise and lighten.
- All-purpose flour
- Provides structure, setting the batter as the proteins and starch cook.
The step that matters
Bake until golden brown. Baking time depends on the oven and the depth of the dish, so color is a better guide than the clock. Baking powder needs heat to rise, and the flour sets as it cooks. Stopping too early leaves the batter gummy, and too long can dry it out.
Swap the apple
How well each one fits the dish's main ingredients (milk, butter, flour):
- Vanillafits better
- Raisinfits better
- Coconutfits better
- Applethe original
Fit is the average pairing score against milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
