Hi Thomasm,
I wouldn't add it to the base but during the final stage of cooking the curry itself. I also add lemon juice to my madras, not sure if you did or not and this is where all BIR's differ around the country.
I was once working up in Glasgow many years ago, being from London myself but now live in the home counties, and once having found our hotel after many hours of trying to find Sauciehall street, which we asked many jocks for the directions!! and none of them would tell us with a wink in their eye and laughing, because its actually pronounced Sockie hall street...... none of them knew where it was... until some glasweigan maiden came to our rescue.... anyway as Ronnie Corbitt always says, "I Diverse".... we eventually found this Indian restaurant on the same street and went to open the door when it suddenly opened in front of us and an Indian guy probably around 7 feet tall said in this broad glasweigan accent, "alright lads wat you havin?" well after we stopped falling about laughing, we had a great time in there and some good eating was had. However....... they seem to serve naan breads up there that are about 3 feet long, we called them elephant ears and had them in the back of the van for about a week or so until we got fed up with them!!!!
So.... If you're ever in Glasgow, look for the jolly "black" giant and get yourself a 3 foot long Naan bread!!
