1. Preheat the oven to 375°F.

  2. Blend the sugar and Instant ClearJel. Add the fruit and cherry concentrate and stir until combined.

  5. Divide the topping among the four dishes of berry filling.

  6. Bake for 30 to 35 minutes for fresh berries, 40 to 45 minutes for frozen berries, until the topping is lightly browned and the filling is bubbly.
