Also prepare two baking sheets with either parchment paper or Silicon baking liners and keep them aside.
In order to make puff pastry, thaw frozen puff pastry sheets overnight in refrigerator or leave one pastry at a time for about 20 minutes on kitchen counter top.
Once Puff Pastry is thawed, work quickly while it's still cold. Flour your countertop or working surface and roll out the pastry sheet to make it 15-20% larger.
With a pizza cutter or knife, cut the puffed pastry into 16 cut rectangles. 8 will be the bottoms of the puff pastry and 8 will be the top.
Take two cut pieces at a time roll them out further to make them even in size.
On one piece place a spoonful of tandoori vegetable curry filling, water the edges with the help of finger. Then place another piece of cut pastry on top of the first and Crimp the edges with the help of a fork to seal all goodness inside.
While shaping and filling, the remaining cut pieces may start to soften, to keep them cold, it would be better to keep them in refrigerator, to keep them cold while working on others.
Repeat the process until all pieces are filled.
Place all the filled pieces on a parchment lined cookie sheet.
Now brush the milk + butter wash on them followed by sprinkling of some sesame seeds.
Now Chill the filled puff pastries in the freezer for at least 20 minutes or up to 1 day.
When ready to bake Preheat oven at 380 degrees F for normal baking and at 340 degrees F for convection baking.
Bake the chilled tandoori vegetable curry puff pastries for 25-30 minutes, or until the tops are golden brown. Make sure to rotate the baking sheet once or twice during bake time.
Remove puff pastries from the oven and allow to cool on the pan until ready to handle and serve.
Wrap each leftover puff pastry up tightly in plastic cling wrap and store in the refrigerator for up to a week.
Left over puff pastries can be warmed in toaster oven, or in air fryer at 200-degree F or in regular oven at 300-degree F for 5 minutes.
