Oh yes, this stuff is amazing. I put a chicken carcass in a pot and added multitude of vegetables- Leeks, Parsnip, yam, squash etc- added salt, garlic, then simmered the hell out of that badboy for atleast half a day. The result is one of the most wonderful things i have ever tasted. It's like some super-juice or something. The vitamineral content is probably great, all those nutrients, all that taste. Sublime.
I strongly recommend y'all invest in some soup loving.
