I just started shopping for backpacking mess kits and didn't have any luck finding any that meet these criteria. I want to be able to clean the items with sand and sterilize with flame.
The kit should have a 1 liter max anodized boiling pot, two anodized cups, and two anodized sporks.
I've seen kits close to this, but they included plastic components which I'd like to avoid.
Anodized means aluminum. Why would you want an aluminum cup? If you want metal, a Sierra cup would work, I used them for decades but they are heavy by today's standards. Sporks are generally plastic but I made one of steel by brazing the end of a fork to the end of a spoon. One liter pots are easy to find.
