Puree 3 cups of chopped seeded watermelon (from a two-pound watermelon). Add a bit of powdered sugar, if you like, and a couple of tablespoons of fresh lime juice, which I left out because I didn't have any limes.
Pop a few blueberries into the popsicle molds before filling with the watermelon mixture. That's it!
I made a version based on Ellie Krieger's recipe in So Easy cookbook, a book I like. Just a little bit. :-)
