Watermelon Slushy (with a little vodka)

Rain came at dinner time and my grilling plans changed to enchiladas. If you make mexican food, you "need" a fruity drink. I was inspired by this post about a blender killing frozen watermelon experiment at Rhubarb and Venison. I loved the idea of freezing watermelon. If you have a normal sized family you can make it through a whole watermelon pretty easily. This is epically true if you, like my sister, have a year old baby who is currently in love with watermelon. No watermelon eatin' baby? No problem. Just dice up your watermelon. Place in a single layer on a cookie sheet and stash in the freezer. Once it's frozen, move to a Ziploc bag in your freezer. Here is my first experiment with frozen watermelon. In a blender combine:

Frozen watermelon (I didn't measure)
Shot of Vodka
tablespoon-ish of lime juice
1 tsp sugar (or to taste)
a fair amount of water. I added maybe as much as 1/2 c.

You'll need lots of water to get the blender moving. You can use tequila or rum or no alcohol if you prefer. Beth at R & V also recommends freezing any fruit you have that is about to go bad. You can turn it into a smoothie later. I need to start doing this. I can be a grown up and admit my fruit will go bad next day and that I'm actually not going to get it eaten in that time.
