Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Custard Pie
Ingredients
Directions
Prepare
Prepare the pie crust before making the custard.
In a bowl, beat the yolks of the eggs until light, then beat the whites separately and combine both.
Add the sugar to the egg mixture and beat well.
Gradually stir in the milk and mix thoroughly.
Add the salt and flavoring essence, or spices if desired, and mix well.
Bake
Fill the prepared pie crusts with the custard mixture, stirring before each filling.
Place the filled pie plates in the oven and carefully fill them to the rims.
Bake until the custard is firm and the crust is golden, protecting the top if it browns too quickly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites set the custard into a firm, sliceable structure as it bakes.
- Milk
- Milk forms the liquid body of the custard, giving a soft, creamy texture when baked.
- Sugar
- Sugar sweetens the custard and contributes to its golden browning on the surface.
The step that matters
Baking until firm. Egg proteins set gradually as the custard heats; underbaking leaves it runny, while overbaking can cause curdling, weeping and a rubbery texture. Watch for a firm set rather than relying on time alone.
