I'll go lurk for a while. 
You're probably joking, but don't do that AST. You've made some great and interesting posts to date; please continue to do so! 
Yep.

Thanks for the feedback though. In this case, "lurking" involved painting, putting up wallpaper, replacing outlet boxes and filling in dents in plaster.
I would appreciate someone posting on this thread an accurate Madras recipe suitable for 200 ml of this particular gravy ... anyone up for it?
SnS, I'll be happy to post where I end up with what I'm doing now, but it isn't quite ready yet (going a bit backwards with the last try, unfortunately). Like you, I took onboard Jeera's comments, but I haven't yet added any garam masala. It'll probably be next week before I get back to the laboratory.

Of course, I suppose the key word here is "accurate"... ;D
