We love the texture that whole pureed fruit takes on when frozen: cold and creamy, just like sorbet. And while lots of fruits will work, we like to pair tropical varieties with ripe summer berries. Whenever you cook or bake with fruit (or any ingredient, really) you should taste a piece before you start to season. In this case, you’ll want to test the papaya and raspberries for sweetness and tartness. If they’re sweeter, dial back the sugar and increase the lime juice. Less sweet? Vice versa. Then taste the mixture once you puree—that way you can be sure the pops freeze exactly to your liking.
