Why it works: Lemon and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Strawberry, Raspberry and Currant Sherbets
Ingredients
Directions
Prepare the juice
Heat the berries in a little hot water for about 5 minutes.
Squeeze the berries through cheesecloth to extract the juice.
To every pint of juice, add the juice of 1 lemon.
Make the syrup
Boil 2 cups of water and 1½ cups of sugar together for 10 minutes.
Freeze
Add the sugar syrup to the berry juices and freeze.
Add the egg white just before the mixture is fully frozen.

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
- Berries
- Provide the main flavour and colour, and the juice that forms the sherbet base.
- Sugar
- Sweetens the base and keeps the frozen mixture softer and less icy.
- Lemon juice
- Adds acidity that brightens the berry flavour and balances the sweetness.
- Egg white
- Whipped into the partly frozen mixture to add lightness and a smoother, airier texture.
The step that matters
Add the egg white just before the mixture is fully frozen. Adding the egg white too early or too late changes the texture. Added while the mixture is still slushy, it blends in and helps trap air, giving a lighter, smoother sherbet. If the mixture is already solid, the white cannot be worked in evenly.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
