2 c. water
1 c. lemon juice (use juice of 2 lemons plus enough reconstituted juice to yield 1 c.)
Zest of 2 lemons, cut very fine
2/3 c. sugar

Heat water and sugar to boiling. Simmer for 5 additional minutes. Remove from heat; stir in lemon juice and zest. Cool to room temperature. Divide mixture evenly among three tubs. Freezer until firm. Shave; scoop into small cups and serve with a spoon or straw. May wish to garnish with a small thin slice of lemon.
