Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Lemon Sheebet
Ingredients
Directions
Make the lemonade
Make a thick syrup by combining 1 pint of sugar with 1 pint of water; heat until dissolved.
Let the syrup cool, then mix in the juice of 6 lemons and enough water to create a rich lemonade.
Make the icing
When the lemonade is half frozen, prepare the boiled icing.
For the icing, moisten 1 pint of sugar with water and boil until it reaches a soft candy stage.
While the icing is hot, add the stiffly beaten egg whites and mix well.
Flavor the icing with vanilla and a little citric acid or cream of tartar, then beat until thick and smooth.
Combine
Fold the icing into the half-frozen lemonade.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into the hot sugar icing to add airy structure and a light, smooth body.
- Sugar
- Sweetens the lemonade and, boiled into icing, helps give the sherbet its body.
- Lemons
- Supply the juice that provides the bright, tart flavor and acidity.
- Citric acid or cream of tartar
- Adds acidity and stabilizes the whipped egg white foam in the icing.
The step that matters
Boil the icing to soft candy stage. Sugar cooked to the soft candy stage sets a firm but tender base that holds the whipped egg whites and keeps the frozen dessert smooth rather than grainy or icy.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, vanilla, cream):
- Strawberryfits better
- Raspberryfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against egg, sugar, vanilla, cream. Candidates are from the same food group and used in at least 100 recipes.
