Agua de Sandia (Mexican watermelon drink)

I was hoping for another glorious weekend, but after sitting inside all week at work looking longingly out the window and tiring of hearing endless news stories about the 'heatwave' whilst viewing it secondhand, it appears to have ended. At least here anyway, and while no means cold, the sun is cosseted in a thick blanket of clouds save for the occasional few seconds peek at what could be... Ho-hum.

So for that reason my mind started wandering on to means of escape and (almost) guaranteed decent weather. Ah... yes. Mexico and my I-hope-it-happens winter break! I'd bought a watermelon on Friday anticipating a weekend of beautiful weather and balmy days sitting under a tree reading and sipping cool drinks. The Mexican aguas frescas are just made for such a day. I'd mentioned them in a previous post, the most popular flavours being agua de horchata (rice milk and cinnamon), agua de jamaica (hibiscus flower) and agua de tamarindo (tamarind). They can, however be made out of just about any fruit, and agua de sandia, made out of juicy watermelons is, as you can imagine a thirst quenching delight that takes almost seconds to make (plus chilling time). Who care's if there's no sun? The colour of the finished drink will brighten up your day.

Ingredients
1 watermelon
2 limes
Agave syrup (or sugar)
Water

1. Peel the watermelon, cut it into chunks and place in a blender. Some recipes say to deseed it first, but really, do you have time to sit and pick out the seeds? 
2. Blend until smooth
3. Squeeze in the lime juice
4. At this point have a taste, some recipes call for a sugar syrup to be added, but I prefer the natural sweetness of the watermelons. I added a little agave syrup as the watermelon wasn't particularly sweet.
5. Strain into a large jug, and taste again. Dilute with water to your own preference and chill for 30 minutes.
6. Serve over plenty of ice, sit back and drink! Incidentally, I used an ice cube tray I'd previously used to freeze batches of green chilli relish and it gave quite a nice tang. For that reason I think serving the agua de sandia with a sprinkling of dried red chilli flakes would work nicely.
