"Nancy and I loved eating at this hole in the wall restaurant in Marina Del Ray called Killer Shrimp. It was in a strip mall and didn't have much character, but their "killer" shrimp drew a loyal crowd. I recently heard that it had closed, so I've tried to recreate it with help from a few others who have tried. I think what most the other versions you'll find online are missing is the true amount of black pepper used. i remember asking them what made it so spicy, and the answer was "lots and lots of black pepper". If you're squeamish about the cup of butter, try using some olive oil instead. I'd at least use a half a cup of butter though, as it adds an irreplaceable richness to the sauce. Enjoy!..."
