Lemon and egg barely smell alike, yet cooks put them together in 44,316 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
- Thicken the mixture as they gently set with heat, giving the cream its body.
- Milk
- Forms the creamy base and provides richness and body for the custard.
- Lemon juice
- Adds acidity that curdles the milk and gives a sharp, bright flavour.
- Lemon peel
- Its oils add a strong lemon aroma that infuses into the milk.
- Sugar (in the method)
- Sweetens the cream and balances the sharpness of the lemon.
The step that matters
Simmer slowly without boiling. Egg proteins set gently at moderate heat. If the mixture boils, the eggs can scramble and turn grainy, so the custard must thicken slowly over low heat.
Swap the lemon
How well each one fits the dish's main ingredients (milk, egg):

- Coconutfits about as well
Fit is the average pairing score against milk, egg. Candidates are from the same food group and used in at least 100 recipes.
