Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Lemon Pie
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Cream the butter and sugar together in a bowl.
Add the grated lemon rind and the egg yolks to the mixture and mix well.
Stir in the cream and the strained lemon juice.
Pour the mixture into a pie crust.
Bake in a slow oven at 300°F (150°C) until set.
Top with meringue
Whip the reserved egg whites.
Spread the whipped whites over the pie for meringue.
Return to the oven until the meringue is 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, and whites whip into the meringue topping.
- Sugar
- Sweetens the filling and helps stabilize the whipped egg white meringue.
- Lemon juice
- Provides the acidity that gives the filling its tart flavor.
- Butter
- Adds richness and tenderness to the filling.
The step that matters
Bake the filling until just set. Egg yolks thicken as they heat, but overbaking makes the custard weep and turn grainy or watery. Baking at a slow oven temperature sets it gently.
