Dan,
I believe that the most natural materials to cook in are either ceramic (like the
Chinese (sappo) sandy pot ,
Spanish terracota cazuela or
Mexican terracota cazuela or
porcelain glass (like
enamelware) , yet you might not want to carry those kinds of pots with you on a long backpacking trip because of their fragility.
Titanium might be dishwasher safe but that doesn't tell us how tough it might be on an extended camping trip, washed in a stream, riverbed, or lake and being exposed to a varying types of cleaning conditions including sand and gravel.
Though a few people have voiced concerns about stainless steel, isn't interesting that most of those people appear to be the ones who are selling things like titanium cookware.
Many more people (especially in macrobiotics) are concerned about aluminum and avoid using pots and utensils with exposed aluminum food cooking and preparation surfaces.
People have been using
stainless steel for several generations now and there are hardly any complaints from the regular users, but if you are really concerned, maybe you can use a ceramic insert like a
Ohsawa Pot in your pots and pressure cooker.
Otherwise, just jump in and be a Titanium Pioneer, and find out for us what using it is like.
And have a good trip!
Thank you, very much.
