Quick Olallieberry Tart

This recipe came from Bon Appetit many years ago.  It originally called for apples, but since I had lots of olallieberries (a kind of blackberry), I used them.  If you have the puff pastry and some fruit around, it's pretty quick, and very yummy!   Don't try to serve more than 4 people with this, or you'll have people asking for more.  The pieces may appear large, but because it is very flat, it isn't really as "BIG" as it seems.  

1 sheet frozen puff pastry, thawed (½ of 17.3 oz pkg)

2-3 cups of berries

2 T unsalted butter, melted

2-3T sugar mixed with ½ t cinnamon (depending on tartness of berries)

¼ C jam, melted (apricot, peach, apple, orange)

Preheat oven to 400^o.  Line rimmed baking sheet with parchment paper.  (You can see that it can get juicy, so you do want sides on the sheet you use.)  Unfold pastry on parchment paper.  Using fork tines, pierce ½” border around edge of pastry, then pierce center all over. 

Arrange berries atop pastry until the entire sheet is covered, leaving border clear.  Brush with melted butter; sprinkle with sugar mixture.  Bake 30 minutes.

Brush melted jam over berries.  Bake until golden, about 8 minutes longer.  Serve warm or at room temperature.  Serve with ice cream.
