Blackberry Sweet Tart Filling


Take any of our sweet dough tart recipes and fill with this delicious blackberry filling. This recipe uses either the fresh or frozen berries and can be used for tarts or cobbler.


  • 1 gallon fresh or frozen blackberries
  • 2 1/2 lb granulated sugar
  • 1/2 glass of water (ONLY if using fresh berries)
  • 6 tbsp cornstarch


Step 1

In a large cooking pot, combine the berries and the sugar. Since frozen berries have a fair amount of liquid, don't add any water. However, if you are using fresh berries, add half a glass of water.

Step 2

Cook over medium heat, stirring occasionally until mixture is somewhat thick.

Step 3

Mix the cornstarch with just enough water to make a soft paste that can be poured.

Step 4

Turn your burner down low and very slowly pour the cornstarch into the blackberry mixture, continue stirring for a minute or two.

Step 5

The mixture will get real thick. Turn the burner off but keep stirring for a few minutes longer. The mixture will look like a thick jelly.

Step 6

Use to fill tarts or make a fresh cobbler.
