1 cup freshly squeezed lemon juice 1 cup water 3/4 cup sugar 1-2 Tbsp lemon zest
Heat sugar and water in a saucepan, stirring until fully dissolved. Remove from heat and add lemon juice and zest. Cool completely. Pour into Tupperware container and put in freezer. Once it begins to freeze, break up ice crystals with a fork and stir to smooth out texture. Repeat once an hour until frozen.
Tip: If you don't have a zester, use a sharp veggie peeler, and then dice w/ sharp knife instead.
