Why it works: Sugar and lemon 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 ↓
Raspberry Sherbet
Ingredients
Directions
Make the syrup
Combine sugar and 1 cup of water in a saucepan; heat until sugar dissolves.
Soak gelatin in a little cold water, then stir it into the hot syrup until dissolved; set aside to cool.
Prepare the raspberry juice
Mash raspberries, pour remaining cup of water over them, and strain through cheesecloth.
Add lemon juice to raspberry juice and mix with cooled syrup.
Finish
Fold in well-beaten egg whites until combined; mixture is now ready to be frozen.

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
- Raspberries
- Provide the main flavour and colour, and their juice gives the sherbet its body.
- Sugar
- Sweetens the mixture and softens the texture by lowering the freezing point.
- Knox's gelatine
- Stabilises the mixture so it holds a smooth, less icy texture after freezing.
- Lemons
- Add acidity that brightens the raspberry flavour and balances the sweetness.
- Egg whites
- Whipped into foam, they lighten the texture and add airiness to the frozen mixture.
The step that matters
Fold in well-beaten egg whites. Egg whites must be beaten to stiff, stable foam and folded in gently so the mixture keeps its air. Overmixing deflates the foam and makes the sherbet denser.
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.
