Why it works: Milk and cheese are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 4,426 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Pennsylvania Cheese 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 the crust
Preheat the oven to 350°F (175°C).
Bake the pie crust until golden brown.
Make the custard
In a bowl, whisk together milk, eggs, and sugar until well combined.
Pour the hot custard into the baked crust.
Sprinkle grated cheese over the custard.
Return to the oven and bake until set.
Make the meringue and finish
In a separate bowl, beat the egg whites with sugar until soft peaks form.
Spread the meringue over the pie and return to the oven to brown slightly.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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 proteins set the custard into a sliceable, firm filling as it bakes.
- Milk
- Forms the liquid base of the custard, giving it a soft, tender texture.
- Sugar
- Sweetens the custard and helps stabilize the whipped egg white meringue.
- Egg whites
- Whipped into a foam that forms a light, airy meringue topping that browns in the oven.
- Grated cheese
- Adds savory flavor and richness to the custard.
The step that matters
Bake the custard until set. Egg proteins coagulate as the custard heats, firming it into a sliceable filling. Underbaked custard stays runny and won't hold its shape, while overbaking can make it curdle, grainy, or weep liquid.
