Great Information Trailrunner thanks.

Yes, you understand perfectly. I have the Snowpeak Titanium 900 which is about 30 oz. Filling this up and bringing it to a boil should make two of the 2-serving Mountain House Freeze dried meals (~16 oz each).

Two canisters it is.

Are there any disposing restrictions on these canisters? I guess I could read up on it but I enjoy the interaction.
