I remember reading, decades ago, one of my father's books, probably published in the 1970s, about budget travel. One thing I read still sticks in my mind today. It said something like, and this is not verbatim but I believe quite close, "the two basic condiments you need to make any food edible are sugar and salt. Salt is cheap anywhere, sugar is not."
It went on to talk about how you should could carry only small amounts of salt, since you could get it cheap anywhere, whereas you should stock up and carry a larger quantity of sugar whenever you happened to be in a place where you could get it cheap. And with sugar and salt on the ready, you should just eat the cheapest possible foodstuff you could come across wherever you happened to be.
Does anybody still travel with that level of attention to budget? My impression is that budget travel these days is about looking for hotel discounts rather than rolling out your sleeping bag and eating out of tins in public parks. Or?
By the way, I would love it if someone could tell me the name of the book!
