A couple of my local groceries sell packed chicken feet, and I absolutely love them for stocks. They’re packed with gelatin and I end up with silky stocks that look like Jello in the fridge. Store rotisserie chickens are also great for stocks in my experience. I get a meal or few out of most of the meat, then you chuck the rest in a pot to turn into stock.
I think at least one of my local groceries also used to sell ox tail. Great for beef stock, but I think it got expensive after it became a trendy cut for some reason. I don’t remember how that happened, I guess people got in the know 🤔.
Goes hard. Gonna save that line for later.
