Onions peel and roughly chop. Wash and clean the chillies and cut them into rings. Wash the meat, dab dry and cut into cubes (approx. 3 cm edge length). Heat the oil in a frying pan.
Fry the meat for approx. 8 minutes, turning it over. After 6 minutes add onions, 2/3 of the chilli and tomato paste. Dust with flour. Deglaze with 1/2 litre water and beef stock. Season with salt.
Close the roaster with a lid and braise in the preheated oven (electric cooker: 200 °C/ circulating air: 175 °C/ gas: level 3) for about 1 1/2 hours. Slice chocolate into thin shavings with a kitchen slicer.
Stir the chocolate shavings into the finished goulash, except for something to garnish. Season to taste with salt. Wash parsley, shake dry, pluck leaves from the stalks and chop. Sprinkle parsley, remaining chocolate shavings and chilli over the goulash.
