i wish i made those...haven't attempted, yet.
usually do 3/4 cup lemon juice, zest of two lemons, 1/2-3/4 cup sugar or agave nectar, 2 cups water...but think my next batch will be something like this.
also quit watching (any olympics) years ago, then i started watching again (kids got into it). i dont get too involved in the patriotic aspect of it as though its a war, instead just admire seeing top athletes perform from wherever they are from, i'll root for whomever is competing...its a hell...
