If using stainless steel molds, you can quickly remove popsicles by running the mold under warm water for a few seconds. 

Choice of sweetener: Agave, honey, or even maple syrup are all viable options, so feel free to use any of those. Since we're using fruit, the popsicles will have a good bit of natural sweetness, so you can leave out the additional sweetener altogether if you'd like.

Choice of berries: We put cherries and raspberries in our pops. Since cherries can be slightly annoying to pit, we'd endorse using strawberries as an alternative there. These would also be great with peaches, nectarines, blueberries, blackberries, or any other summer fruit of your choice.
