I brought a TON of food products, thinking that I wouldn't be able to get those things here, and low and behold, most items were available, and I felt silly bringing a huge box of Nature Valley granola bars when I saw the exact same box for roughly the same price at a local grocery store in UK, knowing that I wouldn't have had to pay for an extra bag if I had left that stuff behind. Some people miss American food more, but honestly, I don't miss it nearly as much as I thought I would. I brought 20 packages of ranch dressing mix, and I have only made it twice in 2 months, and find that I don't like it as much as I remembered... maybe my tastes have changed? I certainly never thought I would swap ranch for brown sauce! And anyway, there are bottles of ranch at the local grocery store, so there you go!
I also brought brownie mix, cookie mix, etc, and most of that stuff is available. (Betty Crocker, even!)
Also, I brought a few baking pans that I didn't really need to bring, they fit in the oven and all, it's just that you can usually find this stuff here and it's not terribly expensive for the regular cookie sheets and stuff. The only pan I brought that I really was glad I brought is a square griddle pan, like for pancakes and such. For some reason, the ones here always have ridges in them. Or maybe its just the ones in this area...
Anyway, ditch the 20 lbs of food, I wish I had....
