A question about Instant Pot technique

[Shel_B]

A few days ago I made I made Chris Young's Costco roast chicken stock: https://youtu.be/3k20zFlbFfE and it blew me away for it's simplicity, cost effectiveness, speed, and flavor. In the video, Chris shows the stock to have been gelatinized, but mine didn't turn out to be so.

 

In my preparation, I used the meat almost two whole chickens, holding back a small amount of meat for a sandwich. I added almost three quarts of water. The result of these amounts caused the pot to fill a fair percentage over the maximum fill line, reducing the head space inside the pot while cooking.

 

My question is this: could the reduced head space affected the formation of gelatin in some way, or reduced the amount of flavor extracted from the meat.

Head space is necessary in a PC to make sure that any kind of boiling/foaming doesn't reach the valves and potentially clog them, which could be catastrophic.  It shouldn't affect the flavor or anything else.  Gelatin doesn't come from meat - gelatin is made from connective tissue - this is why backs, feet, wing tips, etc are great for stock because they have a lot of connective tissue which converts to gelatin after a period of time of moist heat.

@Shel_B How much stock did you end up with?

Just a little less than three quarts of very delicious stock. I will do this again ... and again ...
