To begin making the Mangalorean Style Sonay Sukhe, soak the chickpeas in water for at least 8 hours or overnight.
Pressure cook the chickpeas with water so that it is fully immersed and cook till done. This will take about 25 minutes. Once done switch off the heat and leave it to rest, the pressure will be released by itself. Drain the water away and keep the chickpeas aside.
In a small pan; roast the ingredients for the Bafat powder including byadagi red chillies, coriander seeds, cumin seeds, whole black peppercorns, turmeric powder until you get a good roasted aroma from the coriander seeds. Turn off the heat, cool and grind into a fine powder.
Heat a kadai with oil, add mustard seeds and allow it to crackle, add curry leaves and wait for 5 seconds.
Add the chopped onions, grated coconut and garlic, sauté till the onions are brown. Add bafat powder mix to the sautéed onions and mix well.
Once the spice powder is added, add the cooked chickpea along with the tamarind water and keep sautéing till the water is evaporated and you will get a dry dish. Check the salt and seasonings and adjust to suit your taste.
