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 ↓
Mock Cream 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 custard
Preheat the oven to 400°F (200°C).
Beat together the sugar, cornstarch, and egg yolks.
Bring the milk to a boil.
Stir the egg mixture into the milk.
Add a pinch of salt and the butter, mixing well.
Assemble and bake
Prepare a pie crust.
Bake the crust until golden.
Fill the baked crust with the custard mixture.
Grate nutmeg on top.
Bake again until set.
Top with meringue
Beat the egg whites to stiff peaks. Add 2 tablespoons of sugar.
Spread the meringue over the pie.
Brown the meringue in the oven.

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
- Eggs
- Egg yolks thicken the custard, and egg whites whip into the meringue topping.
- Milk
- Forms the liquid base of the custard, which thickens when heated.
- Sugar
- Sweetens the custard and stabilizes the whipped egg white meringue.
- Cornstarch
- Thickens the custard as its starch swells in hot liquid, giving a sliceable set.
- Butter
- Adds richness and a smooth, tender texture to the custard.
The step that matters
Stirring the egg mixture into the milk. Adding hot milk to egg yolks gradually, while stirring, tempers them so they don't scramble. Cornstarch then needs to reach a boil to fully thicken the custard.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, milk, sugar, flour, butter):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against egg, milk, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
