I plan to fly home with some of my mom's homemade doenjang (Korean fermented soybean paste) and gochujang (Korean chili paste) in my carry-on bag. I was thinking about buying some containers but then saw that some baby food jars are 2.5oz and they're on sale for only $1.39 at Safeway. This cost less than buying empty food safe containers from a store. Of course the food will not be wasted.
I'm curious what other food safe jars/ containers have you reused to take on a carry on. #finance source
