Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Supply the juice and aromatic oil from the peel, giving the ice its sharp acidity and flavor.
- Sugar
- Adds sweetness and balances the lemon's acidity in the finished ice.
- Egg whites
- Whipped to foam, they add airy lightness and body to the frozen mixture.
- Syrup
- Dissolves into the mixture as sweetener and helps keep the ice smooth rather than icy.
- Rum, brandy, and maraschino liqueur
- Add alcohol, which lowers the freezing point and keeps the ice softer and scoopable.
The step that matters
Pouring the boiled syrup over the whipped egg whites. Hot syrup poured slowly while beating cooks the egg whites and stabilizes the foam. Pouring too fast or too cold can leave the whites deflated or grainy.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, syrup, rum, brandy, champagne):
