Pre-911, some coworkers were travelling to DC for a week and staying in a 2-bedroom Residence Inn. They wanted to cook, but had much the same problem: they needed a little bit of this, and a little bit of that.

Their solution was to pack just what they needed to cook with. They were baking a cake for someone so had some vanilla extract, some flour, some sugar, and so forth.

Well, chalk this up to 'seemed like a good idea at the time.' I can tell you that passing through airport security with bags of white powder does not endear you to security screeners. They nearly missed their flight with the half hour interrogation runaround they got. They do kinda look hippie-ish, like they might be potential drug runners, come to think...
