Lemon Ice

Ingredients

Directions

Prepare the flavor

  1. Pare the rinds from the lemons as thinly as possible to cut through the oil vessels.

  2. Heat a little of the water and pour it over the rinds; let it stand to extract the flavor.

Make and freeze the ice

  1. Combine the sugar, lemon juice, and remaining water in a bowl.

  2. Stir in the rinds and the whites of the beaten eggs just before placing the mixture in the freezer.

  3. For a nectar ice, add a little vanilla and currant juice for color.

  4. After stirring until frozen, remove the paddle and repack the ice from the foundation.

  5. Let it stand for 1 to 3 hours before serving, ideally at least 2 hours for a solid form.

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

What each ingredient does

Lemons
Their juice and oil-rich rinds supply the sharp, aromatic flavor that defines the ice.
White sugar
Sweetens the ice and lowers its freezing point so it stays softly textured.
Eggs (whites)
Whites add body and a lighter, more airy texture to the frozen mixture.

The step that matters

Stirring while freezing. Stirring during freezing breaks up ice crystals as they form, keeping the ice smooth rather than coarse and icy. Stir the rinds and egg whites in just before freezing so they are evenly distributed.

Swap the vanilla

The recipe marks vanilla as optional. How well each one fits the dish's main ingredients (sugar, lemon, egg, currant):

  1. Orangefits about as well
  2. Raspberryfits about as well
  3. Raisinfits about as well
  4. Vanillathe original

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