I feel I must post a link to the Whole Life Nutrition website, as I have adopted and adapted so many of their recipes for my kitchen. Here is yet another, for limeade using agave (or honey). We had a bag of limes from Trader Joe's lying around and Elspeth was a bit peeved that Evan and I were having a couple of Pimm's No. 1 Cups (well, peeved that we wouldn't share with her, that is), so I decided to make her her own special drink. She was unsure at first, but seemed to warm up to it. She skipped the limeade part and just referred to it as 'gaveh nekar'. Both Evan and I liked it a lot. I didn't make any adaptations except for making a larger batch. I also skipped making the raspberry ice cubes because I'm lazy that way.
3/4 c. freshly-squeezed lime juice
3/8 c. agave nectar (or honey)
6 c. water
Mix all ingredients in a pitcher and stir. Taste and adjust sweetness, if needed.
