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 ↓
Lemon Pie, Ob Pudding
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.
Prepare the filling
Grate the rind of the lemons, squeeze the juice, and chop the pulp finely.
In a bowl, combine the lemon rind, juice, pulp, sugar, egg yolks, milk, and cornstarch. Mix well.
Bake the pies
Line deep pie plates with puff pastry, fill with the lemon mixture, and bake at 350°F (175°C) for about 30 minutes.
Top with meringue
Beat the egg whites with 6 tablespoons of sugar until frothy.
Once the pies are baked, spread the meringue over them and return to the oven for 5 minutes.

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 filling and add richness and a smooth, custard-like texture.
- Cornstarch
- Thickens the lemon mixture as it heats so the filling sets rather than runs.
- Lemons
- Provide the sharp acidity and bright aroma that define the filling.
- Sugar
- Sweetens the tart lemon filling and helps stabilise the beaten egg white meringue.
- Milk
- Adds moisture and body to the filling, softening its tartness.
The step that matters
Beating the meringue. Egg whites must be beaten with sugar until glossy and stiff enough to hold peaks. Under-beaten whites weep or collapse, while the sugar helps the foam stay stable and glossy during baking.

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