The finest food in the world cannot begin to compete with the taste of home for an expatriate who yearns for Marmite, Hula Hoops and Creme Eggs.
Amid posts debating some of the most pressing matters for those living abroad, expat forums are full of comments about food, reports the Guardian.
Hungry expats discuss where Walkers crisps can be procured and the extortionate prices they are willing to pay just to get their hands on a bottle of Ribena.
Most people will be surprised by which everyday items they miss when they move abroad, even as they begin to love the local products that slowly become part of their lives.
As well as scouring shops and keeping their ear to the grapevine, some have family back at home send these items out to them, but there is another option.
Clare Cook is the woman behind the company British Tuck Box, which sends hampers all over the world to China, New Zealand, Australia and the US for Brits who are feeling homesick for some familiar flavours.
"Walkers crisps, I literally can't believe how many orders we get for them. I've sent whole boxes, just filled with crisps," she told the news provider.
But if you think that it is just the Brits who are silly enough to pack their suitcases full of Yorkshire tea and Percy Pigs, then think again.
Other nationalities are at it too. Italian delis in London sell cured meats and fragrant cheeses to locals and expats alike, but there are certain products that are aimed at those missing their homes in Italy.
Ham-flavoured crackers and cheap chocolate biscuits are pounced upon like rare treasures and instantly reconnect these expats to their childhood.
Patricia Connell of the France in London website said: "Things have improved since I first moved here from France 30 years ago, but you still can't get Les Pailles d'Or biscuits. I miss them. The taste, the smell – everything about them reminds you of home."
