Having spent a serious amount of time in the USA over the past 8 years, the best thing you can ever have with fresh lobster, is melted butter. The combined flavour of these two sole ingredients are mind blowing and I wouldn't change that for the world. We used to eat these with Alaskan King Crab legs, which are even better than lobster itself. If you've never tried that, then you need to visit a great lobster house in the US. A pot of melted butter and the lobster and king crab legs........ just heaven...
However, the best way to enjoy lobster with a curry, is a very mild Tikka Masala sauce, heavy on the coconut and cream, but make it light on the spices so you don't spoil the taste of the lobster. Anything else would be far to strong and given the price of Lobster, would you want to spoil that taste?......
