I am about finished traveling, but for the past 50 yrs I have traveled in Asia and the New World. I have always sought out book shops and looked for the really local tomes put out by churches, civic groups, or women’s groups. They usually run about a buck or so. You might have to work on translations for local items (it’s a nice introduction for talking with the locals), but you’ll remember where you purchased each one and that can be fun it itself let alone cooking from really authentic recipes. And, it gives you a meaningful project for those empty moments on a trip. Start young, as my earliest is from Mexico in 1958.
