Why it works: Orange and lemon 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 ↓
Orange Tartlets
Ingredients
Directions
Make the orange filling
In a pan, combine cold water, sugar, grated orange rind, and lemon juice, and stir until the sugar dissolves.
Add the yolks of the eggs and stir until the mixture just comes to a boil.
Whisk the egg whites until stiff and gently fold them into the orange mixture.
Bake the shells and fill
Line deep tartlet tins with rich short pastry and place a square of bread crust in each to keep them hollow.
Bake the tartlet shells until golden, then remove the bread crust.
Fill the cooled tartlet shells with the orange mixture and garnish with pieces of glace cherries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the orange mixture into a set, custard-like filling as they heat.
- Egg whites
- Whisked to stiffness, they add lightness and airy volume to the filling.
- Sugar
- Sweetens the filling and balances the sharpness of the citrus.
- Lemon juice
- Adds acidity that brightens the orange flavour.
- Orange rind
- Contributes the main citrus aroma and flavour to the filling.
The step that matters
Heating the yolks. Stir the yolks in gently and stop once the mixture just boils. Egg yolks thicken as they heat, but overheating can curdle or scramble them, leaving a grainy filling.
