Watermelon Lemonade on the deck works for me!
Just the thing for a hot afternoon -- the right amount of sweetness, a bit of tart, and even the rich anti-oxidants found in watermelon. I found this recipe on Martha Stewart's blog and had to give it a try. Here's the recipe, tweaked a bit to add a bit more nutrition:
1-1/2 mini seedless watermelons
2 Meyer lemons
large handful of fresh mint leaves
1/2 cup packed brown sugar
Slice open the watermelon and cut the flesh into chunks. Blend in a high-speed blender (like a Vita-Mix) in batches until it's blended smoothly. Quarter the lemons and squeeze the juice into a large pitcher. Throw the lemon rinds into the pitcher, add the mint leaves and the sugar and muddle them until the sugar dissolves into the lemon juice and the mint leaves are bruised. Stir in the blended watermelon. Serve over crushed ice.
Optional: Add 1.5 ounces of premium vodka to the glass with your crushed ice before pouring in the lemonade. Stir well.
