I was going through my Curry Cupboard this morning to look for different pastes and I came across this. I don't know how I've missed it so often and it has actually come with us on at least 1 house move (possibly 2). The original Patak's tin cans have not been available for quite a while but I seem to recall that they did make a good dinner in the day.
Unfortunately it is past it's "best before" date but I only use them as a guide anyway and it's only 5 years.

It shows no sign of rust or deterioration other than on the label so I'm game. I may purchase some breast fillet this arvo and use this to do a side by side with Latif's CTM tonight.
