1. in a medium, heavy pot over medium heat, combine the sugar, butter and water. stirring constantly, cook until it is a thick syrup, about 5 minutes. remove from the heat and pour all over the popcorn. stir to coat evenly.
2. turn onto a sheet of parchment paper to cool. 40 minutes, until pie filling is nice and bubbling.
notes: add sugar slowly and taste. if your fruit is really sweet, you may not need 1/2 cup of sugar. you can always add more sugar if your fruit is tart.
