Preheat the oven to 220°F
Prepare two baking sheets with silicone mats
Add fruit to a blender or food processor and puree it
Add the fruit puree to a pan on the stove and heat until it reaches a slow boil
With a Pamona's Pectin package, prepare the calcium to water ratio to store in a separate jar in your cupboard
Once your calcium/water ratio is ready, add the calcium to the the pureed fruit and stir, and turn the heat down low
In the blender, combine the Ramona's pectin and lemon juice together very well for 2-3 minutes
Stir in the Panama's pectin/lemon juice mix into the fruit on your stove top
Pour the mixture onto the prepared baking sheet with a silicone mat until the amount on the silicone mat is roughly a side plate size
Carefully tip the baking sheet from side to side allowing the fruit mix to spread out across the entire silicone mat. The end result should be a fruit layer about the size that you wish your fruit roll ups to be, as the depth won't change too much during baking
Bake in the oven for 40 minutes or until completely dry (the thicker the leather the longer it will take to dry out)
Remove leather from the oven and slice into long strips.
Roll strips into circles and store in a container
