Why it works: Milk and corn match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 6,953 recipes mention both. Both carry hexanal, which smells green, grassy. The science ↓

The recipe

Ingredients

Contains: egg, milk (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Make the custard

  1. In a saucepan, heat the milk over medium heat.

  2. In a bowl, beat the 2 remaining egg yolks and mix in corn starch and sugar.

  3. Gradually add the hot milk to the egg mixture, stirring constantly.

  4. Return the mixture to the saucepan and cook until thickened, stirring frequently.

Make the meringue and serve

  1. For the frosting, beat the reserved egg whites until stiff peaks form.

  2. Drop spoonfuls of the beaten egg whites into boiling water and cook for a few minutes.

  3. Remove the egg whites and place them on top of the custard.

Milk and sugar share little aroma chemistry, yet 77,855 recipes mention both: they likely 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

Milk
Forms the liquid base of the custard that thickens when cooked.
Eggs
Egg yolks thicken the custard, and whites whip into the meringue topping.
Corn starch
Thickens the custard by swelling in the hot liquid.
Sugar
Sweetens the custard and helps stabilize the beaten egg whites.

The step that matters

Gradually add the hot milk to the egg mixture, stirring constantly.. Adding hot milk slowly and stirring keeps the egg yolks from scrambling. Gradual tempering raises their temperature evenly so the custard thickens smoothly.
