Why it works: Milk and lemon 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
two good sized piesIngredients
Directions
Make the filling
Separate the yolks from six eggs.
Beat the yolks with two cups of pulverized sugar until well mixed.
Add two and a half cups of milk, the juice of three lemons, and a little salt; mix well.
Bake the mixture until set.
Top and brown

Beat the whites with one-half cup of pulverized sugar until well mixed.
Spread the sugared egg whites over the top of the baked pie filling.
Brown the whites in the oven.

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 it sets, and whipped whites form the browning topping.
- Lemons
- Lemon juice adds acidity that sharpens the sweet filling.
- Milk
- Adds moisture and body to the filling.
- Pulverized sugar
- Sweetens the filling and helps stabilize the beaten egg whites.
The step that matters
Browning the topping. Sugar in the egg whites browns quickly, so the topping can scorch before it colors evenly. Watch it closely and remove it once golden, because prolonged heat toughens the egg proteins and can make the topping weep.
