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 short crust pastry.
Make the filling
Stew the diced pumpkin with a little water until tender.
Add sugar and lemon juice to the pumpkin and mix well.
Assemble and bake
Brush the pastry with egg white.
Pour the pumpkin mixture into the pastry and bake until the crust is golden.

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
- Provides the bulk and soft, smooth body of the filling once stewed until tender.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness of the filling.
- Sugar
- Adds sweetness to balance the tartness of the lemon and the mild flavour of the pumpkin.
- Short crust pastry
- Forms the structural base that holds the filling and bakes to a golden, crisp shell.
The step that matters
Brushing the pastry with egg white. A thin layer of egg white seals the raw pastry so the moist pumpkin filling is less likely to soak in and leave the crust soggy during baking.
Swap the pumpkin
How well each one fits the dish's main ingredients (lemon, sugar):
- Orangefits better
- Limefits better
- Vanillafits better
- Pumpkinthe original
Fit is the average pairing score against lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
