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 Meringue 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
Preheat the oven to 350°F (175°C).
In a saucepan, melt the butter and add water, sugar, cornstarch, and salt. Stir until smooth.
Cook over medium heat until thickened, then remove from heat.
In a bowl, beat the egg yolks and gradually add the lemon juice and zest.
Combine the egg mixture with the thickened mixture and pour into a pie crust.
Bake for 10 minutes until set.
Top with meringue and bake
In a clean bowl, beat the egg whites with cream of tartar until stiff peaks form.
Spread the meringue over the pie filling, sealing the edges.
Bake for an additional 10 minutes until the meringue is golden.

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 enrich it, giving it a rich, custard-like body.
- Cornstarch
- Thickens the filling as it cooks, giving it a smooth, sliceable set.
- Lemon juice
- Adds the sharp acidity that defines the filling's bright flavour.
- Egg whites
- Whipped into a foam that forms the light, airy meringue topping.
- Sugar
- Sweetens the filling and helps stabilise the whipped meringue.
- Cream of tartar
- Stabilises the whipped egg whites so the meringue holds its peaks.
The step that matters
Cook the filling until thickened. Cornstarch only thickens fully once it reaches a boil and the mixture has cooked long enough. Undercooked starch leaves a runny filling that will not set when cut.
