Recently I have been doing a few shorter Ultra-Lite hikes (1-2 nights) without bringing a kitchen.
In the food bag I’ve brought nuts, flapjacks, sausages, cheese, snicker bars, digestive biscuits etc. High energy and compact foods ready to eat.
So what are the advantages? Well, I save a lot of weight (pot, spork, lighter, fuel, stove, wind screen), volume and worries.
Without kitchen, I am able to choose a smaller pack to carry my gear in. The hike becomes more basic, I move through nature in a way closer to the other animals. I don’t have to worry about running out of gas, esbit tablets or alcohol. Leaking alcohol bottles is not an issue. I don’t have to clean any pots or wait for my food to get ready. More time to hike and sleep.
For me, the biggest downside is not getting my caffeine kicks from coffee. But, I try to tell myself that I’d be better off if I could get rid of that addiction. (And besides, there are for example chocolate-covered roasted coffee beans to snack on.)
I won’t head out without a kitchen in sub-freezing temperatures, but for 3-season, I think I’ll do without fire for more and more trips.
The body-warming effect of a cup of soup I think is easily compensated for by movement. Jump around camp for a minute or two before sleep and in the morning and you will get the blood flowing.
Have you tried this approach? If not, why not give it a go?
