The most flavorful, full-bodied chicken stock takes hours to make on the stove — usually. Here's a shortcut that doesn't compromise on quality: add packets of unflavored gelatine to your stock ingredients and have stock in less than an hour.

In his massive and highly informative new book, The Food Lab, Serious Eats' J. Kenji Lopez-Alt explains that chicken stock gets its body and texture from the chicken's connective tissue. When heated up, the collagen in the connective tissue turns into gelatine, but it's a chemical process that takes hours.
Kenji's scientific shortcut? Add packaged gelatine to finely ground chicken carcasses (specifically, chicken backs and wing tips pulverized in a food processor) and your other standard chicken stock ingredients, such as water, onions, celery.
45 minutes of cooking plus the time to skim off excess fat, and you've got a rich, flavorful chicken stock that would fool anyone into thinking you cooked it for hours.
I tried it this weekend and it was the quickest way I've ever made homemade chicken stock and soup.
