I don't do this and likely would never do this not because in itself it sounds like a bad idea but it's a personal preference of really disliking the ideas of FaceTime video chatting things.

Now on the other hand socialized cooking is something that I actually do but in person. Prior to covid it was actually a weekly thing friends and family would get together and we would cook together. Sometimes it would just be cooking together various dishes to form a meal but sometimes it would be what we call cooking challenges. And in that respect we would all make the same or a very similar dish or the core idea was the same and then we will try it and decide which we liked best.

So overall I don't think this would be a bad idea and a lot of people would probably enjoy it.
