Wash and drain the beef well.
On a hot saucepan, on low heat, roast all the ingredients under "spices to roast" for a few minutes or till aromatic.
Add onto the beef, sprinkle in salt and toss well to coat all over. Marinate for 15 minutes or as long as possible.
In a pressure cooker, heat coconut oil. Fry the ginger garlic paste for a couple of minutes.
Add the onions and green chillies and saute till wilted.
Add the tomatoes and cook till all mashed up.
Now add the marinated beef along with a glass of water (ideally the water cleaning up any residue marination in the bowl), add more salt if needed.
Cook for 5-6 whistles or till the beef is nicely cooked.
Once done, sprinkle in the garam masala and add the coriander leaves if using.
Heat oil for tempering. Splutter the mustard seeds and fry the dry chillies and curry leaves. Add in to the curry, allow it to rest for five minutes.
Serve hot with neychor or flatbread of choice.
