I haven't been to Goa yet and I don't remember anyone praising the food there much, but this dish has every reason to be praised. So simple, tasty and user-friendly! No gluten, eggs, nuts or lactose. I'll definitely make it more often.
I have also tried it with chicken fillet and it was just as well received. I saw this a few years ago on a food program on the plane to India, it wouldn't surprise me if I added some of my own spices. I don't remember exactly. If you don't have dried chilies, you can use chili powder if you like. You need a good food processor or a good mortar and pestle and it sounds like a lot with so much vinegar, but remember that it's a large portion. It's a bit strange not to finish with a sprinkle of coriander, but if you want, you're welcome :)
