Wash and peel the asparagus and cut off the woody ends. Cut the asparagus diagonally into thick slices and cook in little boiling salted water for about 5 minutes. Drain on a sieve and let cool.
Also drain the mandarins and collect the juice. Clean and slice the mushrooms. Cut 4 slices of smoked pork loin into strips. Mix crème fraîche, 2 teaspoons of curry, 1 tablespoon of lemon juice, 3 tablespoons of mandarin juice, some salt, pepper, sugar and Worcester sauce.
Fold asparagus, up to 8 tips, mushrooms and mandarins into the sauce. Allow to soak a little. In the meantime clean, wash and drain the salad. Roll up the remaining slices of smoked pork loin into small bags and put them into 1 asparagus tip each.
Line 4 glass bowls with salad leaves. Season the salad again and put it into the bowls. Serve garnished with smoked pork.
