I'd suggest getting a few and trying them out at home! That should resolve your questions, including if you find the results edible! I find the Knorr stuff far too salty, but I am used to a low-salt diet at home.

With dried milk, be sure to mix it thoroughly in cold water before using. If any lumps are left, they will get worse during cooking.

I suspect the reason for the larger pot is to prevent boiling over when cooking noodles. But you'll find out in your home trials!
