Why it works: Corn and milk are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 6,955 recipes. Both carry hexanal, which smells green, grassy. The science ↓
Corn Starch 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
Combine corn starch, milk, egg yolks, and sugar in a saucepan.
Cook over medium heat, stirring until it thickens like custard.
Pour the mixture into deep plates and bake at 350°F (175°C) until set.
Make the meringue and finish
Beat the egg whites until stiff peaks form, then gradually add 3 tablespoons of sugar.
Spread the meringue over the baked custard and brown it under the broiler.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the milk mixture into a custard as it heats.
- Egg yolks
- Enrich and thicken the custard, adding richness and structure when set.
- Egg whites
- Whipped into stiff peaks to form the meringue topping.
- Milk
- Forms the liquid base of the custard.
- Sugar
- Sweetens the custard and stabilizes the whipped egg whites.
The step that matters
Cooking the custard until it thickens. Cornstarch thickens only when the mixture reaches a simmer and is stirred constantly, so undercooked custard stays thin and may not set after baking. Stirring prevents lumps and scorching on the pan bottom.
