Step #2 Place the salmon in large baking pan, pour the white wine over the salmon, cover & bake for 1 hr.
Step #3 Warm the oil in a small non-stick pan and, when it is hot, sauté the onion & garlic over a medium-high heat, stirring, until it has begun to soften.
Step #4 Set aside until needed.
Step #5 Remove the salmon from the pan & allow it to cool.
Step #6 Break the salmon into small pieces & mix it with the sour cream, garlic & dill, onion, & mix until all the ingredients are well-mixd.
Step #7 Lay one sheet of puff pastry on a greased baking sheet, & spread the salmon mixture over the pastry leaving a 1/2 inch border along all sides.
Step #8 Top with the remaining puff pastry sheet, & crimp & seal the edges.
Step #9 Brush the top of the pie with egg wash (1 egg white mixed with 1 tsp water) & bake it for approximately 1 hr or until the top has begun to lightly brown.
Step #10 Notes: Because salmon obviously vary in size, use your culinary judgement when adding the sour cream.
Step #11 Add a little at a time.
Step #12 You don't want the filling to be too liquidy but you do want it moist.
Step #13 If you have extra puff pastry, you can make decorative shapes on the top of the pie.
