Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Merton College 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).
Juice the lemon and combine it with sugar, water, egg, cream, and flour in a bowl. Mix until smooth.
Bake and serve
Pour the mixture into a prepared pie crust.
Bake for about 30-40 minutes or until set.
Let cool before serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Sets the filling into a firm custard as it bakes.
- Flour
- Thickens the filling so it holds its shape when sliced.
- Sugar
- Sweetens the filling and balances the lemon's acidity.
- Lemon
- Provides the tart, acidic flavor that defines the pie.
The step that matters
Bake until set. Underbaked filling stays runny, while overbaking can make an egg-set custard weep and turn grainy. Checking for a firm set at the stated time helps the filling finish cleanly.
Swap the lemon
