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 Honey Tartlets
Ingredients
Directions
Make the filling
In a saucepan, combine sugar and butter.
Grate the yellow rinds of the oranges and add to the mixture.
Squeeze in the juice of the oranges and lemons.
Stir and boil, then add the eggs.
Cook on low heat until the mixture thickens like melted cheese.
Fill and serve
Use the cooled mixture to fill tartlet shells or spread between cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the mixture as they cook and set it into a smooth, spreadable filling.
- Butter
- Adds richness and a smooth, silky texture to the filling.
- Sugar
- Sweetens the filling and helps balance the sharp citrus flavour.
- Oranges
- Provide the main fruit flavour and juice, with zest adding aroma.
- Lemons
- Add acidity that brightens the sweetness and balances the filling.
The step that matters
Cook on low heat until the mixture thickens. Egg yolks and whole eggs set as they heat, but high heat can curdle them into grainy lumps. Gentle heat and steady stirring give a smooth, thick custard-like filling.
