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 ↓

Sugar and lemon 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
- Sugar
- Adds sweetness and body to the filling.
- Eggs
- Their yolks thicken the filling as it cooks and give it a rich texture.
- Lemon
- Provides the acidity and aroma that flavour the filling.
- Milk
- Adds moisture and softness to the filling.
The step that matters
Cook in a double boiler, stirring constantly until it thickens. Egg yolks can curdle or scramble if they get too hot. A double boiler spreads gentle heat, and constant stirring keeps the yolks evenly warmed so the filling thickens smoothly.
Swap the orange
How well each one fits the dish's main ingredients (sugar, milk, lemon, egg):
- Vanillafits better
- Orangethe original
- Figfits about as well
- Blueberryfits about as well
Fit is the average pairing score against sugar, milk, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
