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 ↓
Lemon 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
Grate the peel of the lemons and juice one of them.
Make the filling
In a bowl, combine the lemon zest, lemon juice, pounded almonds, preserved lemon and orange peel, powdered sugar, and beaten eggs. Mix all ingredients together until well combined.
Bake
Line a baking dish with fine pastry and pour the mixture into it.
Bake in a moderate oven at 350°F (175°C) until set.

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
- Eggs
- Set the filling into a firm, sliceable custard as they cook.
- Pounded almonds
- Add body and a rich, nutty texture to the filling.
- Powdered white sugar
- Sweetens the filling and balances the sharp citrus.
- Lemons
- Supply the zest and juice that give the tart its bright, acidic flavour.
- Preserved lemon and orange peel
- Add concentrated citrus aroma and a bittersweet depth.
The step that matters
Bake until set. Eggs thicken as their proteins coagulate with heat. Underbaking leaves the filling runny, while overbaking can make it curdle, weep or crack, so check for a firm centre rather than relying on time alone.
