Add the frozen fruit to a blender and blend until it resembles crushed ice. Transfer to a small sauce pan.

Add the sweetener and 1 cup of water.

Over medium heat, bring the fruit mixture to a boil, stirring constantly. Make sure that the sweetener dissolves completely.

Once a boil is reached, turn off the heat. Place a fine mesh strainer over a large measuring cup. Pour the fruit mixture into the strainer and use a spoon to stir the fruit as it is pushed through the strainer. This may take up to 5 minutes.

All of the fruit has been strained when there is 2 cups of liquid in the measuing cup and a jam like substance left in the strainer.

In a seperate measuring cup, dissolve the gelatin into cold water. Pour the gelatin mixture into the fruit mixture and stir well.

Pour the unset jello mixture into any dish, bowl, casserole dish, etc. Any size will work.

Carefully place in the refigerator. Let set until firm about 3 hours.
