Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange Tart
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Boil the grated rind and pulp of the oranges with the lump sugar until thick like marmalade.
Bake the mixture in the pastry for an open tart at 300°F (150°C) until set.
Let the tart cool completely.
Top and finish
Beat the egg whites to stiff peaks, spread them over the cooled tart, and sprinkle pounded sugar on top.
Bake in the oven until browned, about 20 minutes.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Seville oranges
- Provide the bitter, acidic flavour and the pectin that thickens the filling.
- Lump sugar
- Sweetens the filling and, as it cooks down, helps it set thick like marmalade.
- Egg whites
- Whipped to stiff peaks, they form a light meringue topping that browns in the oven.
- Pastry
- Forms the crisp base that holds the thick orange filling.
The step that matters
Cook the orange mixture until thick. The filling must be boiled down to a thick, marmalade-like consistency before baking, because it sets only as far as it has thickened. Thin filling will stay runny in the tart.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Orangethe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
