So here we cobbled together two flavors of our own: mango-lime-banana and raspberry-lemon-peach. The secret ingredient according to Laney is, of all things, club soda added at the end. Here is a basic recipe for you to try now that you can probably find all kinds of molds on sale around town. (We got ours via Amazon and the sticks on a last-minute dash to Michael's craft store tonight.)
2 c fruit, sliced (you can blend berries first and then strain out the seeds if you want)
1/4 c sugar
1 lemon or one lime, juiced
1/2 c club soda
Blend first 3 ingredients in food processor. Add club soda and pulse. Pour into molds, add sticks, and freeze for 3 hours. Let them sit out on the counter for a few to thaw for easier removal. Possibly never buy boxed popsicles again.
