Does Chris Young's Costco rotisserie chicken broth only work well because of pre-injected broth?

If you haven't seen Chris Young's rotisserie broth recipe: https://chrisyoungcooks.com/pressure-roast-chicken-stock/ This recipe really changed my broth game and I make it once a week now. But I recently roasted my own chicken and tried the same method, and the broth ended up much less gelatinous. Not saying it was bad by any means, but it got me thinking - is it just basically quick and easy meat jello because Costco pre-injects their chickens with their own broth? And that is making its way into my own broth? If you refrigerate a Costco chicken, there is always some very gelatinous broth at the bottom of the bag. Just putting two and two together here. submitted by /u/volkovolkov [link] [comments]
