hi phil lol i work for the RM and they do a 9 o'clock special delivery which should be guaranteed to be delivered by 9am the next morning, if you put your frozen container in a polystrene box with a tight fitting poly lid it should still be frozen mate ;D by the time you get it.
jerry a masala sauce and tandoori tikka marinade are different terrys' was the marinade. have you tried the red masala paste i posted years ago? and the korma paste, for a CTM i would use a combo of the 2. and try powder rather than the block at least you will be able to have better control on the sweetness ie sugar.
regards
gary
