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 ↓
Marlborough Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Steam or bake the apples until tender.
Press the cooked apples through a sieve while hot.
Add the butter to the apples and let the mixture cool.
Beat the yolks of the eggs.
Mix the yolks with the milk, sugar, lemon juice, and lemon rind.
Combine the yolk mixture with the apples and butter.
Bake and top
Line a dish with pastry.
Fill the pastry with the apple mixture.
Bake for 1 hour at 400°F (200°C).
Whip the egg whites until stiff, adding a little sugar.
Heap the froth over the pie.
Return the pie to the oven to set the meringue.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cooked and sieved, they form the soft, moist body of the filling.
- Eggs
- Yolks thicken the filling as it bakes, while whites whip into the meringue topping.
- Butter
- Adds richness and a smooth, tender mouthfeel to the apple filling.
- Milk
- Adds moisture and body to the custard-like yolk mixture.
- Lemon
- Juice and rind add acidity and bright aroma that balance the sweetness.
The step that matters
Let the apple mixture cool before combining with the yolks. Eggs thicken when heated, so adding yolks to very hot apples can scramble them and leave a grainy filling instead of a smooth, set custard.
Swap the apple
How well each one fits the dish's main ingredients (butter, egg, lemon, milk, sugar):
- Vanillafits better
- Figfits better
- Peachfits about as well
- Applethe original
Fit is the average pairing score against butter, egg, lemon, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
