Rinse a large container of blackberries. Organic is best, but you'll live to see another day if you buy regular.

Rinse and cut the tops off of a bunch of strawberries.

You'll need a blender

Grab a handful of the blackberries (do your best not to eat all of them before they hit the blender)

Now the strawberries. It always helps to put the softest food in the blender first so the blades can puree it and then suck the food on top down faster.

Make sure the lid is sealed extra tight. Especially when dealing with stain-happy berries

Blend to a nice thick but pourable consistency. Add a bit of water to help get started (no more than 1/3 cup or you'll have to use way too much sweetener)

Agave nectar is a healthy alternative to sugar, and blends effortlessly. I got mine from Whole Foods.

Don't be shy with it - especially with such a large amount of berries.

after blending the agave in, be sure to taste it to make sure it's not too tart

Pull out the popsicle molds. I got these from Target in their seasonal clearance bin for 75 cents. Seriously.

Oh well, messy is kind of fun

And there you have it. Tasty little frozen goodness.
