Refreshing in the Summer Heat!

Ever since I was a little girl, I have loved the scent of lemon balm (Zitronenmelisse). My mom grew it in our garden, but I can't remember what (if anything) she made with it. I'll have to check with my sister to see if she remembers.

Now, we grow several bushes of lemon balm, which is easy to do as it likes to reseed freely. Every few days, I pick a good handful of stems and leaves, add about 4 cups of boiling water, and let that steep for about 10 minutes. I then strain the infusion into a 1/2 gallon pitcher and fill the rest with ice and water. And voilà!
You have a very refreshing summer drink! Enjoy!

Is there something you make to keep you hydrated in the summer heat?
