Preheat oven to 400 degrees F.

Roll the pastry out into a thin rectangle; cut lengthwise into 2 long strips.

Divide sausage into 2 portions, dust with flour, and form long rolls about the same length as the pastry.

Place sausage in the middle of the pastry strips; brush pastry edges with milk, then seal the long edge.

Brush the two pastries with milk, then slice into 1 to 2 inch rounds.

Place rounds on a baking sheet and bake for 15 minutes at 400 degrees F; reduce heat to 350 degrees F and bake until puffed and golden, about an additional 10 to 15 minutes.
