Idk about the Knorr product but if you want home-made taste with no additives or preservatives give this stuff a try www.morethangourmet.com/our-prod....
i like this stuff. cheap, tasty, better than powdered, can control the liquid level. it's an awesome starter for egg drop soup. thanks for the recommendation for the fancy version, @LocalStain
I tried that Knorr crap and it was horrible. If I haven't made the stock, I use the "Kitchen Basics" stocks to cheat. They sell them in 1 cup containers when I don't need 4 cups.
