Carefully lift both out with a skimmer and let them drip off well on kitchen paper. Wash the fillet and dab dry. Heat the oil in a frying pan and fry the fillet thoroughly all around.
Season with salt and pepper. Take out and let cool down a little. Put the roast with the gravy aside. Lay the puff pastry slices on top of each other and roll out in double the size of the fillet.
Chop half the thyme. Mix pâté and chopped thyme. Spread the fillet with it. Place strips of vegetables around the fillet like roof tiles. Place the fillet on the puff pastry and wrap in it. Cut off any protruding edges, roll out and cut out ornaments.
Whisk the egg yolk and cream, brush the dough with it. Place ornaments on top, spread them on the dough as well. Bake in the preheated oven (electric cooker: 200 °C/ convection oven 175 °C/ gas: level 3) for approx. 25 minutes.
Heat the meat and deglaze with stock. Bring to the boil and thicken with sauce thickener. Simmer sauce for about 1 minute. Season to taste. Broccoli with almonds is delicious with it.
