Use your chopping board to cut your beef into stewing chunks. Season it with a teaspoon of salt, curry powder, turmeric, smoked paprika and black pepper and allow it to marinate for at least 30 minutes or overnight for best results.
Using your blender, process onion, the remaining salt, tomato, red bell pepper and tomato puree.
Use a pestle and mortar to crush the garlic and ginger.
Under high heat, heat a medium-sized pot or pan then add the oil. Add the beef chunks and allow them to brown (about 2-5 minutes) on each side. Turn and allow the other side to brown for about 2 minutes, then stir in the crushed garlic, ginger, and tomato paste. Fry for a further 2-5 minutes until brown and fragrant then add the blended tomato mixture and stir.
Simmer for 30-45 minutes (see notes below), stirring from time to time. You can add water, a little at a time, if you prefer more sauce or if your pan feels too dry. Also check for salt and pepper at this point and add some more, if preferred.
Garnish with some coriander or parsley. Serve while hot and enjoy with your favourite side dish.
