Philadelphia-Style Lemon Water Ice

By Mark Huxsoll

Published on April 28, 2025

Time

25 minutes, plus 1 hour freezing

Yield

Serves 4 to 6

Philadelphia-Style Lemon Water Ice

Ingredients

7 lemons 2 cups water, divided1 cup (7 ounces/198 grams) sugar ⅛ teaspoon table salt

Before You Begin

If using a canister-style ice cream maker, be sure to freeze the empty canister for at least 24 hours before churning the water ice. For a self-refrigerating machine, pre-chill the canister by running the machine for 5 to 10 minutes before pouring in the blended fruit mixture.

Instructions

  1. Place 8½ by 4½-inch loaf pan in freezer. Using sharp paring knife or serrated knife, cut away peel and pith from lemons; discard peel and pith. Chop lemon flesh (you should have 3 cups chopped fruit); discard seeds. 
  2. Process prepared lemon flesh, ½ cup water, sugar, and salt in food processor until very smooth, about 1 minute. Strain lemon mixture through fine-mesh strainer into large bowl or liquid measuring cup, pressing on solids to extract as much liquid as possible; discard solids. Whisk in remaining 1½ cups water. 
  3. Transfer lemon mixture to ice cream maker. Churn until mixture has consistency of grainy soft serve, 15 to 25 minutes. 
  4. Transfer water ice to chilled loaf pan. Cover and freeze for at least 1 hour or up to 1 month. Serve. (If water ice is too firm to scoop, let sit at room temperature for 5 to 10 minutes before serving.)

Why This Recipe Works

Water ice, a classic Philadelphia summertime treat, is a frozen fruit-based dessert with a texture that’s softer and slushier than granita but more crystallized and granular than sorbet. To get this texture, we carefully tinkered with the sugar-to-water ratio: Too much sugar and the texture was too creamy; too much water caused the mixture to freeze solid. Ice cream machines mimic the industrial machines that water ice shops in the Philadelphia area use, quickly freezing the mixture while scraping the sides of the canister to yield uniform ice crystals.
