Poke a hole lengthways through the two pork fillets using the handle of a wooden spoon as thick as a finger. Season the well-squeezed spinach with salt, pepper and a little garlic and use it to fill the pork fillets. Salt, pepper.
Fry in the fat (oil and butter) while still hot, then fry in a hot oven over medium heat (approx. 160 - 175 ° C) for approx. 12 - 15 minutes until juicy.
Add the shallots to the roast residue in the pan, sauté briefly, deglaze with white wine and beef soup and reduce to a third. Fold in the crème fraîche, bring to the boil briefly and season with mustard, salt and pepper. Stir in the cold butter.
Cabbage vegetables and ribbon noodles are tasty as a side dish.
