Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pumpkin Tart
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.
Prepare
Preheat the oven to 350°F (175°C).
Line a pie plate with the short crust pastry.
Make the filling
In a pot, stew the diced pumpkin with a little water until tender.
Add sugar and lemon juice to the pumpkin and mix well.
Bake
Brush the pastry with egg white, then pour the pumpkin mixture into the crust.
Bake the tart until the crust is golden brown.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 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
- Pumpkin
- Forms the main body of the filling and provides moisture and sweetness once cooked.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness of the pumpkin.
- Short crust pastry
- Forms the crisp, golden base that holds the filling.
The step that matters
Bake the tart until the crust is golden brown. Baking until the crust browns fully sets the pastry so it stays crisp under the moist pumpkin filling. Pulling it early can leave a soggy base.
