I have gotten my kitchen kit down to just a mug pot and an alky stove and I do all my eating and tea/coffee drinking out of my mug pot. But as I plan for my CDT thru-hike I have been considering adding another mug/cup so that I can eat and drink hot drink at the same time to save time (especially breakfast), as well as being able to use a slightly larger pot (0.9 vs. 0.6 L) for my larger thru-hiker appetite.
My question is, does anybody have any ideas for a ~14-16 oz plastic bowl/cup/jar/bottle that has a wide mouth and a screw on lid? I would like this piece of gear to be multiple use as a water bottle to supplement my platy bladder and I was thinking I could rehydrate bulger salads for lunch in it too while I walk if it had a wide mouth. I found an empty peanut butter jar yesterday that I thought was perfect size and shape, but it doesn't seem to hold its shape when boiling water is added (funny experiment this evening). It was recycle symbol 1, which I have since learned is NOT good for hot water.
Whether the item is food safe at boiling water temperatures is obviously very important. Thanks in advance for suggestions.
And FWIW, I tried eating out of the ziplock bags during my PCT hike and quickly found that it is both unpleasant and easy to spill on my down sleeping bag (4 nights from Mexico). I respect that other people eat out of them, but I would rather eat out of the pot.
