No problems with moving the files, in fact that is a good idea.
I cannot put my finger into what it was missing, when I ate it at about 5 pm (my time). However, at about 8 pm, I was starting to feel hungry again and the vindaloo was still on the cooker (it was still in my non-stick Ikea work, with the lid on top). It had cooled down and so i got a spoon and ate a spoonful. WOW! It had really come to life!!
I've known about this for years, that if you make a curry, leave it too cool down, over night, and then heat it up the following morning that it is so much better.
For lunch I'm meeting a friend for dim sum, so the earliest I'll be able to finish the remaining vindaloo will be tonight. So, I'm going to make another batch tomorrow, but this time I'm not going to eat it there and then, but I'm going to leave it for a few hours, then heat it up and then eat it.
Having left it to stand for a few hours and the eating it, it was as good as anything I've eaten when I was in England. if this theory is correct, then I'll be making more, leaving it to cool, putting it into Zip-loc bags, and freezing it, to see if that works.
