Why it works: Orange and walnut are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,058 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Orange Tart
Ingredients
Directions
Prepare the filling
Squeeze, pulp, and boil the Seville oranges until tender.
Weigh the oranges and use double the weight in sugar.
Beat the oranges and sugar together to form a paste.
Add the juice and pulp of the oranges and the butter, then beat until combined.
Assemble and serve
Line a shallow dish with the puff pastry and fill it with the orange paste.
Optionally, ice the tart before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Seville oranges
- Provide the bitter, acidic flavour and the pectin that helps the paste set.
- Sugar
- Sweetens the bitter oranges and, with the fruit, thickens the paste into a set filling.
- Butter
- Adds richness and a smoother, glossier texture to the orange paste.
- Puff pastry
- Forms the crisp, flaky shell that holds the orange paste.
The step that matters
Beat the oranges and sugar into a paste. The paste must be beaten until smooth and thick enough to hold its shape. Too little cooking or beating leaves the filling runny, while the sugar and the fruit's pectin together are what allow it to set firmly when cooled.
Swap the orange
How well each one fits the dish's main ingredients (sugar, walnut, butter):
- Vanillafits better
- Figfits better
- Coconutfits better
- Orangethe original
Fit is the average pairing score against sugar, walnut, butter. Candidates are from the same food group and used in at least 100 recipes.
