Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Custard 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).
In a bowl, whisk the egg yolks with milk and season with coarse sea salt.
Pour the mixture into the pie crust.
Bake the custard
Bake in the hot oven until the crust is lightly browned.
Reduce the oven temperature to 350°F (175°C) and bake until the custard is set and not curdled.
Make and brown the meringue
Beat the egg whites until frothy, then add sugar and spread over the custard.
Return to the oven to brown the meringue.

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
- Set the custard and give the filling its structure as it bakes.
- Milk
- Forms the liquid base that turns into a soft custard when heated.
- Sugar
- Sweetens the meringue and helps it brown in the oven.
The step that matters
Bake the custard until just set. Egg proteins set as the custard heats, but overheating makes them tighten and curdle, leaving a grainy, watery texture. Lowering the oven temperature gives a gentler set.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
