This was very good. I doubled the recipe. ! used a pound of wild mixed mushrooms that I thawed and drained thoroughly. I used a couple of different ingredients. I didn't have the brandy or cognac, so used Marsala wine and I only 1/4 cup for the two recipes as it's very strong. I used plain Silk Soy Creamer instead of heavy cream and added some goat cheese and grated Romano cheese in the mushrooms. I also used goat butter as opposed to cow's milk butter. I used the tarragon because I have some growing in my garden and I used both sheets of my puff pastry. I made 18 squares and turned them over. I brushed them with some egg replacer (Nu Laid) to seal the edges and coat the tops. I baked the mushrooms in the pastry as per the directions on the package. These came out so nice and turned a golden colour. Thank you for this recipe. I will make it again.
