Ingredients
1 cup lemon juice, from about 6 lemons
1 cup plus 2 tablespoons sugar
2 cups water
1 cup (3 1/2 ounces) diced apple (about 1 apple), cut into 1/4- to 1/2-inch pieces
1 1/2 pounds ice
1 pound rock salt
Preparation
In a blender, combine the lemon juice, sugar, water and diced apple. Blend the ingredients until smooth.
Place the lemon mixture in a small metal bowl over a larger bowl containing the ice and salt and whip with a hand whisk for about 10 minutes to lighten the texture, or to desired consistency.
Freeze the gelato base for about 11/2 hours before serving.
