1 cup water
1 cup sugar
Juice from 4-6 lemons
4 cups cold water
Blend 1 cup water and 1 cup sugar well in small saucepan. Bring to a boil, stirring frequently, until sugar dissolves completely. Let cool and refrigerate. (This is the simple syrup.)
Mix the simple syrup well with the juice from 4-6 lemons (strained or not, as you like) and stir well. Add 4 cups cold water and mix. Try using sparkling water for some fizz! Pour into thermos or large jug, adding thin lemon slices if you’d like, or garnish with mint sprigs.
