Why it works: Milk and corn 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 ↓
Lemon Pie
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Preheat the oven to 300°F (150°C).
Dissolve the corn starch in the milk.
In a bowl, combine the egg yolks, sugar, salt, milk, lemon juice, and lemon rind.
Pour the mixture into a pie crust and bake slowly until set.
Make the meringue and finish
For the meringue, beat the reserved egg whites until stiff, then gradually add 6 tablespoons of powdered sugar.
Spread the meringue over the pie and bake until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling as they set; whipped whites give the meringue its airy structure.
- White sugar
- Adds sweetness and balances the sharpness of the lemon in the filling.
- Corn starch
- Thickens the milk so the filling sets smooth and sliceable rather than runny.
- Lemons
- Juice adds acidity and tang; rind adds aromatic lemon oils for flavour.
- Sweet milk
- Provides liquid and richness, giving the filling a soft, creamy texture.
The step that matters
Bake the filling slowly until set. Egg proteins set gently at low heat. If the oven is too hot, the filling can curdle, toughen, or weep liquid, so a slow bake keeps it smooth.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, milk, corn):
- Vanillafits better
- Coconutfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against egg, sugar, milk, corn. Candidates are from the same food group and used in at least 100 recipes.
