Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Lemon Pie with Two Crusts
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Beat the lemon juice, grated rind, sugar, and egg together for 10 minutes.
Rub the butter and corn starch together until well combined.
Mix the butter and corn starch with the other ingredients and add the water. Stir until well mixed.
Bake
Pour the mixture into a deep pie pan lined with pie crust and cover with a top crust.
Bake in a hot oven at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Adds structure and richness, helping the filling set when heated.
- Corn starch
- Thickens the liquid into a filling that holds its shape when cooled.
- Sugar
- Sweetens the filling and balances the sharpness of the lemon.
- Lemon juice
- Provides the acidity and bright lemon flavour of the filling.
- Butter
- Adds fat for richness and a smoother mouthfeel in the filling.
The step that matters
Stir the corn starch fully into the mixture before baking. Corn starch must be evenly dispersed to thicken properly; lumps left in the filling stay dry and gritty, and uneven mixing leads to a filling that does not set uniformly in the oven.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, butter, corn, milk):

Fit is the average pairing score against sugar, egg, butter, corn, milk. Candidates are from the same food group and used in at least 100 recipes.
