Wash lemon grass and cut into pieces. Wash and chop the coriander. Wash chilli and cut into fine rings. Mix vinegar, honey, oyster sauce, lime juice and zest. Gradually add oil drop by drop.
Season with salt and pepper and stir in lemon grass, chilli and coriander. Warm up the marinade (approx. 50°), let it cool down. Strain 6-8 tablespoons as dressing through a sieve and chill. Marinate the shrimps in the remaining marinade for approx. 30 minutes. Coarsely chop the peanuts and roast them in a pan without fat until golden brown, take them out. Clean the Pak Choi, wash thoroughly and drain. Cut Pak Choi lengthwise in half and stew in a pot with little salted water for 4-6 minutes until firm to the bite. Heat up a coated pan. Put marinated shrimps into the pan and fry them at medium heat for 3-4 minutes, depending on size. Drain Pak Choi, rinse with cold water, dab dry with kitchen paper and mix with the dressing that has been set aside.
