Why it works: Lemon and milk are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Gold 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 filling
Grate the lemon peel and squeeze the juice into a bowl, removing all seeds.
Add sugar, milk, cornstarch, and beaten egg yolks to the bowl and mix well.
Pour the mixture into a pie dish and bake without an upper crust at 350°F (175°C).
Top and finish
Beat the egg whites to stiff peaks, sweeten them, and pour over the baked pie.
Return the pie to the oven to stiffen the egg white topping.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they 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
- Egg yolks
- Thicken the custard and add richness to the filling.
- Egg whites
- Whip into a stiff meringue topping that sets and browns in the oven.
- Cornstarch
- Thickens the milk and lemon mixture as it heats.
- Sugar
- Sweetens the filling and the meringue topping.
- Lemon
- Adds bright acidity and aroma from its peel and juice.
The step that matters
Beating the egg whites to stiff peaks. Egg whites must be beaten until stiff and free of any fat or yolk, because fat blocks foam formation. Properly stiff whites hold air and set into a stable topping instead of weeping or collapsing.

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