Frozen Lemonade

On a hot day, it's hard to drink a tall glass of liquid frozen lemonade. Combine sliced lemon, extra-fine sugar, water, and lemon juice with ice to create a frozen drink that the whole family will enjoy.
Combine 1 thinly sliced lemon and 1/2 cup extra-virgin sugar in a bowl; mash with a spoon. Add 3 cups cold water and 1 1/4 cups lemon juice; let stand for 5 minutes, stirring occasionally. Strain it. Combine half of the lemon juice mixture and 4 cups of ice in a blender until smooth. Pour into 4 chilled glasses; repeat. Submitted by
