Ingredients: 1 quart red raspberries; 1 quart water; Juice of 2 lemons; 1 pound sugar; 2 egg whites (optional)

Why it works: Lemon and egg are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 43,327 recipes mention both. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓

Lemon and sugar share little aroma chemistry, yet 53,530 recipes mention both: they likely 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: Sweetens the mixture and lowers its freezing point, keeping the ice softer.
Lemon juice: Adds acidity that brightens the raspberry flavour and balances the sweetness.
Egg whites: Beaten and folded in, they add lightness and an airy texture to the ice.

Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
