I was trying to recall all the items in my travel bag (which is not yet unpacked after my return from Saskatoon late last night) - and had a flashback to having mentioned it on eG way,way back. A little research led me to this thread.
So my little zippered bag hasn't changed - still has cutting board, paring knife, serrated knife, forks, spoons, pepper grinder, corkscrew and can opener. And I bring teapot, cup, water boiler - this trip I brought a bag of milk in an insulated lunch bag. Hotel had a great little kettle so boiler stayed in suitcase.
My suitcase has Ziplock bags in it all the time.
A trip that involves chocolate has a much bigger list.
