Take the tenderloin out of the refrigerator a quarter of an hour in advance.
Very quickly brown the tenderloin on the pan over smoking high heat.
Put the browned tenderloin in a vacuum bag.
Vacuum pack the bag.
Place the pork tenderloin in your sous vide and let it cook for 1 hour at 58°.
Then take the meat out of the water bath and unpack it from the bag.
Dry the meat well.
Wrap the meat and place it in the freezer for 1 hour.
Finely chop mushrooms, onions, and garlic in a food processor and season with salt and pepper.
Put the mushroom mixture in a dry pan and let it boil. All moisture must evaporate, so the mixture ends up being completely dark.
Place cling film on the kitchen counter and arrange the Parma ham in a square.
Spread the mushroom mixture on the Parma ham.
Take the pork tenderloin out of the freezer and brush the surface with mustard.
Place the pork tenderloin on top of the mushroom mixture.
Roll it all up with the help of the cling film.
Place the roll in the fridge for 30 minutes to "set".
Remove the film and place the roll on the puff pastry.
Roll the puff pastry around the roll and brush with plenty of egg.
Score the puff pastry with a knife and bake in the oven for 20 - 25 minutes at 200°C fan oven until it looks golden and crispy.
Take your finished pork Wellington out of the oven and serve!

Notes
It turned out really delicious ??? I just made too few mushrooms ??♂️ They were sold out at the local supermarket ? Next time, I will double the amount to 300 grams of mushrooms per tenderloin.
