Orange and Lemon Ice

Ingredients

Directions

Make the base

  1. Grate the rinds of the oranges and steep them in slightly more than 1 pint of water for a few moments. Strain the mixture to obtain 1 pint of orange-infused water.

  2. Combine the orange-infused water with 1 pound of sugar and 1 pint of lemon juice.

Freeze and finish

  1. Pour the mixture into a freezer.

  2. When it is half frozen, fold in the beaten egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oranges
Grated rind adds fragrant citrus aroma and flavor from its oils.
Sugar
Adds sweetness and lowers the freezing point, keeping the ice softer.
Lemon juice
Provides acidity and a bright, sharp flavor that balances the sugar.
Egg whites
Whipped to a stiff froth, they add air and a light, airy texture.

The step that matters

Fold in the egg whites when half frozen. If the mixture is still too liquid, the whites deflate and sink; if it is fully frozen, they cannot be folded in evenly. Half-frozen gives a slushy base that holds the whipped air.

Swap the orange

How well each one fits the dish's main ingredients (sugar, lemon, egg):

  1. Orangethe original
  2. Vanillafits about as well
  3. Limefits less well
  4. Raisinfits less well

Fit is the average pairing score against sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
