I'm sure it's quite a common thing for expats - you spend a few weeks, maybe even a few months in a new country, enjoying the new cuisine and learning all about it. However, at some point, possibly when feeling a little low or a little homesick, you'll have a yearning for the taste of something from your home country. Maybe something you used to eat often, maybe something you tended to just eat as a child, maybe a special drink, but chances are there'll be something!
If you're lucky, it'll be something popular enough in your new country that you'll be able to find it in a large supermarket, and your cravings for the taste of home can be sated.
If you're unlucky though, and the bigger shops round you don't stock it, what then? What strategies can you use to get hold of some of whatever "foreign" food it is you're after?
