I agree that improvising solutions is "part of the fun," but there are things you can't help taking for granted. When I was in Japan, I used a Kim Chi mix to make myself beef tamales. Masa Harina was available, but chili powder wasn't. Never found chili powder(or Masa) in Sosua come to think of it. Brown and serve sausage(AKA "cat turds") only made me crave Jimmy Dean sausage in natural casings and REAL maple syrup.
When I got to craving pizza, I ended up making bruschetta instead~ fresh basil is cheap to make pesto and the plum tomatoes are usually excellent. That, some crappy locally made French bread and some parmesan made for some good eats hitting all the bases for pizza. But on my next trip, I'll be bringing my own pizza stone as well. You adapt with what's on hand and then work to a better solution when you can get the materials you want.
