Roast beef with mustard

Keep the roast beef in one piece, just remove the bones and veins, pierce the meat and put pancetta strips in it.

Add salt and pepper (seasoning to taste), brown it in hot lard for a few minutes, rub it with mustard, add a bit of garlic and cook covered over low heat pouring in water and wine.

When the meat turns tender, add flour to the lard and after a few minutes pour in some water, when it boils add cooking cream, bring to a boil and then pour over the meat cut into thin slices.

Sprinkle parsley leaves over the meat.
