Yum, yum! This was sooo good! The sauce is excellent for dipping chapatis in, too. I made this tonight for my birthday dinner and everyone loved loved loved it. I only made one change, which was to leave out the chilies and instead add a few drops of hot sauce. Oh wait, I made one more: I can't get fresh coriander or green cardamoms, so I used dried herbs in place of those. Also, my nuts never did quite form a "paste" per se...it was more like a very fine meal, maybe because I dried them too much after boiling? I think that next time I would put out a little pot of the coriander and cardamom on the table for people to sprinkle on the shrimp when served; adding it at the end made it become lost in the sauce and one did not get to fully appreciate the neat flavours from those spices along with the shrimp. Thanks for such a delicious recipe, Charisma!
