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 ↓
Custard 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.
Make the custard
Beat the eggs until light and fluffy.
Mix the hot milk with the beaten eggs and sugar.
Add vanilla or other essence for flavor.
Prepare the crust
Line a pie dish with the pie crust.
Brush the crust with the egg white.
Bake
Pour the custard mixture into the pie crust.
Bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate as they bake, giving the custard its set structure.
- Hot milk
- Forms the liquid base that gives the custard its moisture and creamy texture.
- Sugar
- Adds sweetness and helps soften the set custard's texture.
- Pie crust
- Holds the liquid custard in shape while it bakes.
- Egg white
- Brushed on the crust to help form a barrier against sogginess.
The step that matters
Bake until set. Eggs thicken as their proteins coagulate with heat. Overbaking tightens them too far, which can make the custard grainy, curdled, or weepy.
“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.
