Is your pan sauce below par?

A very important difference between restaurant and home made pan sauces is the amount of gelatin in the stock. Restaurants make their own stock and it is full of natural gelatin from the bones. Most home chefs use store bought stock/broth or make it from bouillon which has no gelatin.
