Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Ideal Custard Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Beat the eggs until well mixed, then add the milk and vanilla.
Mix the sugar, nutmeg, and salt together, then add to the egg mixture.
Line a pie pan with flaky pastry and sprinkle 1 teaspoon of flour in the bottom, rubbing it in with your fingertips.
Bake
Pour the custard mixture into the crust.
Bake in the hot oven for 8 minutes.
Reduce the heat to 300°F (150°C) and bake slowly until the custard is set, testing with a silver knife.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it structure and body.
- Sweet milk
- Provides the liquid base that gives the custard its smooth, tender texture.
- Sugar
- Adds sweetness and helps keep the custard tender as it bakes.
- Nutmeg
- Adds warm aroma and flavour to the custard.
The step that matters
Bake slowly until the custard is set. Eggs thicken as their proteins coagulate, and high heat can make the custard curdle, weep or puff and turn rough. Lowering the oven temperature lets it set gently and evenly, so testing with a knife before removing it prevents a runny centre or overbaking.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, milk, sugar, vanilla, flour):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Turmericfits less well
Fit is the average pairing score against egg, milk, sugar, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes.
