It was drilled into my head by my grandma to always have emergency supplies in the kitchen. The kit was always a few bottles (gallon jugs) of drinking water, tins of spam, corned beef or other luncheon meat, ramen, tins of campbell's soup, parmalat milk, jello mix, matches in a waterproof box and a bunch of beeswax emergency candles and a small steel mug to cook something in. If I take something out of the kit, my priority was to get the item replaced asap.

My modified version of grandma's list includes microwavable campbell soups, individual packets of spam instead of tins of spam and multiple juice box sizes of parmalat instead of the huge carton and of course chocolate puddings Some of the ramen has been substituted with cup noodles where you just add hot water.

Most of this stuff I wouldn't touch usually but it's there mostly to prevent acid stomach from irregular meal hours and to help with jetlag. I do an inventory every new years to I make sure it's all within date.

Depending on my flight schedule, sometimes I bring cup-noodles on trips where I know that I'll be arriving after room service has closed for the night and there is nothing nearby. A granola bar, is good for breakfast but somehow I burn it too quickly for dinner.
