Why it works: Cream and butter 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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg whites until stiff peaks form.
Heat the cream and pour it over the beaten egg whites.
Make the filling
In another bowl, mix the lemon peel, lemon juice, egg yolks, butter, and sugar.
Combine the mixtures and pour into a pie crust.
Bake
Bake until set, about 30-40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and set the filling, while beaten whites add lightness and structure.
- Butter
- Adds fat for a rich, smooth texture and mouthfeel.
- Sugar
- Provides sweetness that balances the tart lemon.
- Lemon
- Juice adds acidity and the grated peel adds fragrant citrus aroma.
- Cream
- Adds moisture and richness, giving the filling a soft, creamy body.
The step that matters
Bake until set. Egg proteins firm as they heat, so the filling sets. Overbaking makes the custard tight, grainy, and prone to weeping liquid, while underbaking leaves it runny.
