I've been trying to find the restuarant vindaloo for years ! Most of my recipes are similar to the ones on here..I take it most people "graduated" like me from the Pat Chapman books through to the Khris Dillon books..still searching for "the secret".
My curries are usually very nice, I try small experimentation around Khris Dillon type recipes, mostly adding black pepper, tamarind etc to find the hot and sour taste that I like the best.
If I get close, I'll post it.
