Blend each fruit separately and then pour in bowls (strain the seeded fruit if you prefer). For a chunkier texture, you can mash softer fruits with a fork instead.
If you want to add any sweetener, then pop it straight into the blender with the fruit. Start with 1/2 tbsp per fruit and increase, to taste.
Pour a little of each fruit mixture into the popsicle molds. You can layer them in whatever order you prefer but I like strawberry, mango, pineapple, kiwi, and finally, blackberry. Tap the molds lightly on a surface between pouring each layer, to get rid of any air bubbles.
Insert popsicle sticks in the middle of each one and then freeze for at least 10 hours, until fully set.
How To Store: You can keep these frozen treats in the molds for up to 2 months. If you're wanting to re-use the molds or de-mold them, then lay them on a tray and freeze till solid and then transfer to air-tight bags/containers. Make sure they're not touching or they will stick together.
The total time does not include setting/freezing time. It's best to leave the lollies in the freezer for about 10-12 hours.
Read the 'what to add' section for ideas of additional ingredient choices, sweeteners, creamy elements, alcohol, and more.
Blend the fruits whole and pour straight into the popsicle molds or blend and strain, for a smoother end result.
If you want to add sugar to your rainbow popsicles, then I suggest using a natural sweetener like maple or agave. You could also use erythritol or stevia if preferred. Sugars actually help to lower the freezing point of the popsicle, which will help to make it softer.
If you decide to add a creamy yogurt then you create a nice 'tie-die' effect by running a knife up the side of the mold a few times before inserting the stick.
For a different style of real healthy popsicles, dice/slice the fruit and add to the popsicle mold along with the liquid of your choice ( i.e.coconut water for coconut popsicles). These will be 'harder' popsicles and will take longer to melt while consuming. But look beautiful and still taste lovely.
