OK, I made mine (the ridged one). On yours, does the lid still fit well after you cut it with a side-cut can opener? Mine seems a little loose. Right now, I think I like the slightly larger capacity of the Almond can better. I think even for solo, I'd like to be able to comfortably boil one cup.
BTW, with the bean-dip pot and a tea-light stove, I got 1 cup to boil in 5:40 in my kitchen.
