I used coconut by Coyo, you can also use Anita’s. If you cannot find those I suggest a tangy unsweetened one you can find that suits your fancy, and it doesn't have to be coconut. // You can also use dairy yogurt if that is your jam, just remember unsweetened is the way to go if you want a sugar-free popsicle or a Greek yogurt. If you want more sweetness-feel free and use a yogurt that is already sweetened. // You must use frozen berries otherwise the water ratio will be different and I didn’t test it that way.
