Nectarine and Concord grape tart

A quick tea-time snack or dessert for pastry lovers.

Many local fruits are plentiful in September in Ontario.  Among these are concord grapes and nectarines. For this recipe I have used organic produce grown by local farmers but any fruit you have on hand works for this simple open faced tart done with puff pastry.
Note:  I always have ready-made puff pastry in the freezer and this can be taken out and thawed in a few minutes on your counter when needed.

Ingredients

Ready made puff pastry (defrosted as per package instructions)
1 nectarine thinly sliced
1 cup of concord grapes
1/4 cup marmalade, peach jam or jam of choice plus 1 teaspoon water
1 tablespoon of butter (optional)
1 teaspoon sugar

Instructions

Preheat oven to 425 F
Line your baking sheet with parchment paper or foil.
Thaw the puff pastry as per the package instructions

Roll out the pastry to whatever size your pastry calls for.  It does not matter if the sheet you use is square or rectangle.
Place the pastry on a baking sheet lined with parchment paper.

Lift the edges roughly to form a lip around the edge of the pastry.  Pinch the corners to close.

Heat the jam for 10 seconds in the microwave and then spread it on the rolled pastry.

Lay the nectarine slices along the edge of the pastry sheet and work your way towards the middle.
Sprinkle the grapes on the top.

Put little pats of butter on the top of the fruit.  Sprinkle with the sugar.

Bake for about 10 - 12 minutes  until the pastry is brown and puffy.
