Preheat oven to 350 degrees F.
Season fish portions with salt and pepper. Place 1/2 of an egg sliced in the middle of a 6 by 4-inch piece of puff pastry, then cabbage, cooked. Top with basmati rice mixed with mushroom duxelle, fines herbs and last the fish. Make sure that each layer is very even.
Moisten the edges of the pastry with a bit of egg wash. Pull the sides up on top of the fish, pinch together, then repeat with the ends. Repeat for each individual portion. Decorate the top with fish shaped pastry cut-outs, wash with egg wash. Bake for 16 minutes.
Heat asparagus in butter with a mashed garlic clove. Season lightly with salt and pepper and add chervil. Place the asparagus in the middle of the plate without the butter. Cut the fish portion in 1/2 and place on top of the asparagus so that the cut sides show. Remove the garlic clove from the reserved butter and add in the caviar. Mix the caviar gently and spoon evenly to sauce each plate.
Melt butter in saucepan. Add minced onions and saute until translucent. Add mushrooms and porcini and cook until liquid has evaporated. Add vermouth and slowly cook until evaporated. Add sour cream, bechamel, chives, and spices.
Bring water to a boil with shallot and salt and simmer until shallot is tender. Whisk in butter and lemon juice.
