Line a large cookie baking sheet with parchment paper.
Roll out thawed puff pastry to remove the seams at the folds. At all times make sure that the pastry is chilled. Place on parchment paper and start working with the first pastry sheet while the second one keeps refrigerated.
Once the puff pastry sheet is rolled out, choose a 10 or 12 inch dinner place and cut all along using a sharp knife. You will be left with a circle once you remove the trimmed edges.
Spread the cold samosa filling evenly on the sheet leaving about 1 inch from the edges. You can smoothen out the filling using a spatula. Return to fridge while you start working on the second puff pastry sheet.
Using the same dinner plate you used for the first sheet, cut out a circle from the second puff pastry sheet. Brush some water on the edges that we left out on the first sheet and place the second sheet to sandwich the samosa filling. Seal the edges by pressing down lightly.
Place a juice glass in the center. Press slightly to form a circular impression but not all the way through. Now starting outwards from the edge of centre circle, cut 4 quarters to begin with. This will help you keep the rays of equal size. Next half each quarter and proceed to half those halves. You should have 16 rays.
Once the rays have been sliced, carefully lift the rays (you can use a spatula) and twist the rays inwards bringing the end part to flatten on the parchment. Once all the rays have been twisted, use a fork and crimp the flat end part.
Generoulsly Brush the tart with melted butter (this will help in golden baking) and sprinkle some cumin seeds in the center. Chill for 20 minutes.You can store the assembled tart for upto 1 day.
Preheat oven to 400. Bake the tart for 23-26 minutes until goldebn brown. Once baked, let stand for 10 minutes and serve with chutney.
