A refreshing treat

It's hot.
Crazy hot — triple digit.
Now, I've endured these seventh-circle of hell summers every year since I was 6. So what makes it so hard to stand now? I just got back from San Diego. The thermometer never rose above 75. Seriously, if it weren't for the insanely tight and in short supply parking, I could do S.D. But, I failed the parallel part of my driving test. And, many, many years later, I haven't improved.
But, at least we can visit. And when we can't, we make watermelon juice. It's simple, delish and might actually be more refreshing than the fruit itself. Really.
You basically whir up watermelon cubes with water and add sugar to taste. The drink packs the taste of a heavy nectar but is thin, like juice. The top gets foamy and pulpy, and you can easily strain it, but I like the little bits. Sprinkle a touch of salt on top, and it's even better.
Try it.

Watermelon Juice
4-5 cups of cubed watermelon
5 cups of cold water
3 tablespoons (or more) sugar

First, put 2 cups of water in the blender. Add the watermelon. Whir it all up. Sprinkle the sugar; taste. I've added up to 1/4 cup of sugar — it just all depends on the sweetness of the melon.
Pour the puree into a pitcher along with the rest of the water. Serve with a light dusting of salt and enjoy. Pretend you're on vacation somewhere cool.
