Heat 2 to 3 tbsp vegetable oil in a pressure cooker and add some whole spices like bay leaves, cloves, cinnamon, and cardamom.
At the same time add pieces of red whole chillies, finely chopped ginger, and garlic cloves. Saute this for at least 30 seconds and then add the onions that are cut into quarters. Continue to saute until the onions turn translucent.
Then add the beef pieces that are washed and drained. Also, add turmeric powder and salt to taste. Fry the beef along with the onions and spices for 3 to 4 minutes to sear up the meat. Now add 3 tbsp vinegar and freshly crushed black pepper and mix well.
Now cover the pressure cooker and allow the beef to cook. After one or two whistles, reduce the flame and cook on a low flame for approx 25 to 30 minutes.
After the cooker has cooled down, open the lid. You will find that the meat and onions have released a lot of moisture. It is best to transfer this into an open vessel or Kadai and dry up the liquids on a very high flame.
When the black pepper beef is almost dry, then switch off the flame.
Serve with Prathas, Naan or Rotis.
