Rule of thumb is using as much onions as you have meat. Regarding the meat - invest some time to remove the sinews - its worth the effort.
Roast the onions golden, than add paprica and caraway.
Add the meat an roast the meat from all sides.
After about 3-5 minutes roasting add some water so all of the meat is covered.
Now simmer at around 1-1/2 hours depending on the quality of your meat. Near finishing time add the vinegar and simmer for another 5-10 minutes.
Best Served with salt potatoes or buns.
Also a beer (in a separate glass to drink) should be added ☺
