Blueberry Turnovers

this recipe was such a hit, i decided to do blueberry.

Ingredients:

2 lbs frozen blueberries
1 tbsp butter
1/3 cup brown sugar
1 tsp nutmeg
1 tsp salt
1 lemon juiced
2 tsp xanthan gum (use cornstarch as an alternative about 2 tbsp?)
2 sheets puff pastry

Put the first 6 ingredients in a sauce pan, uncovered, high heat for 15 min.  Turn the flame off and put in the xanthan gum.  Mix thoroughly.  Place aside.

Place each sheet of puff pastry on a floured surface.  Then cut it into four squares.  Fill each with the filling.  Brush each piece with melted butter.

Bake on 350°F for about 20 - 25 min.

When cooled, dust the roll ups with powder sugar.
