To start off, I would suggest you get a mixing bowl, usually they are made in stainless steel but you may find aluminum or copper. Modify that and when you are happy with it, get hold of the Snow Peak Trek Titanium Bowl, (1.90z ,holds 20oz) and finish you project with this one (if you are also after a very light solution)
For a strainer, just drill a few tiny holes on the lid.
No handles, use a pot holder.
I posted this on another forum but thought that could inspire someone here too..
