Separate the frozen slices of puff pastry and remove the sheets of paper between them.
Coat one side with egg yolk and place the slices back on each other so that they once again form
a single block. Freeze them slightly, then cut slices from the block using a ruler and a sharp knife.
Place the slices on a baking sheet and brush lightly with egg yolk. Sprinkle with salt. Bake in the
oven at 200°C for 6-8 minutes. Store in a well-sealed container.
Pickle the sea bass fillets for 30 minutes in salt water. Pat them nice and dry and smoke the fillets using an electric smoke tube for 30 minutes.
