Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Pumpkin Tart
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the pastry
Make a puff pastry with the flour and line a shallow tin pan with it.
Grease the pan well and prick the pastry to prevent blistering.
Bake at 400°F (200°C) until golden, then turn out of the pan.
Make the filling
Boil 1 pound of ripe yellow pumpkin until soft, then pass through a sieve.
Add ½ cup sugar, grated lemon rind, lemon juice, orange juice, and cloves.
Boil until the mixture is clear, then remove the cloves.
Assemble and serve
Fill the pastry case with the pumpkin mixture.
Cover with whipped cream and sprinkle with chopped pistachio nuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pumpkin (in the method)
- Forms the bulk of the filling and sets into a soft, smooth custard-like texture when boiled and sieved.
- Sugar
- Adds sweetness and helps thicken the filling as the mixture is boiled.
- Lemon
- Adds acidity and aroma from the rind and juice, balancing the sweetness of the filling.
- Coombs' eureka flour
- Forms the structure of the puff pastry case that holds the filling.
The step that matters
Boil the pumpkin mixture until clear. Boiling the sweetened pumpkin purée drives off excess water and thickens it. Stopping too early leaves a runny filling that soaks the pastry, while overcooking can make it stiff.
Swap the nuts
How well each one fits the dish's main ingredients (flour, sugar, lemon, orange, clove, cream, pistachio):
- Almondfits better
- Cashew nutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against flour, sugar, lemon, orange, clove, cream, pistachio. Candidates are from the same food group and used in at least 100 recipes.
