Dab meat dry and cut into cubes. Heat the oil in a frying pan. Fry the meat for about 6 minutes while turning. Peel onions and cut into cubes. Add the onions to the meat and fry for about 5 minutes, turning, deglaze with stock, mustard and cream, season with salt and pepper.
Bring to the boil and braise covered over a low heat for about 1 3/4 hours.
Wash the celery, dab dry and cut into large pieces. Wash apples, cut into eighths, remove core. Cut mustard gherkins into large cubes. Add celery, apples and mustard gherkins to the goulash after about 1 1/2 hours.
Wash the chives, dab dry and cut into fine rings, except for something to garnish.
Bring the goulash to the boil, stir in the sauce thickener, bring to the boil again and simmer for about 1 minute. Season sauce again with salt and pepper. Sprinkle goulash with chives and garnish.
Onion bread tastes good with it.
