Thanks for the feedback on the Grains. yes on Googling it does reference back to Africa.
I am trying to source some (no pun..)
As for the tinned fruit, yes I saw it in Undercover as well. it does make sense as I have seen the odd grape floating in the Red Sea, although it is not a dish I'd choose. But if there is a dish on the table, its always worth a dip with some bread
I popped in to my local to ask about the "household" products in use. They seem quite unabashed by using whatever is available. Lemon was courtesy of PLJ (pure lemon juice). I seem to remember as a child this was advertised on TV! Aziz confirmed the Grains of paradise are used sparingly as a garnishing spice, in the vain of garam massala. as the research shows, the ginger/cardamon theme is already present from other ingredients.
Ok here was the surprise. Marvel. yes, that nasty milk powder. he uses a spoon of it in the Cream type dishes (CTM/Korma/Pasanda etc). it thickens the gravy and gives a creamy texture and I guess cheaper than cream. cream is used as garnishing swirl on the sweet Red stuff. I'm all for shortcuts, but this seems a corner cut too far. Having said that, it tastes really good. I'll try and get more detail on quantity and method of the "grains"
