Are you in a studio or a 1br? In a 1 or 2 bd I have pretty much allthat I need, I just bring zip lock bags, asst sizes and a few folded sheets of aluminium to line baking sheet/pans! Salt and pepper, coffee and filters!
But in a studio where everything is plastic I would recommend packing in your checked in suitcase if you fly, a paring knife to cut apples, hard cheeses etc.!
