Pan drippings are the concentrated flavors left in a pan after cooking meat or poultry. These wonderful juices are often incorporated into sauces, stews, or gravies to elevate their taste complexity. They also allow for a waste-less meal, as you're using elements that would otherwise be washed away.
What makes them a must-have in your kitchen is their ability to impart a depth of the meaty savoriness to your dishes that can't be replicated by store-bought broths or stocks. Blending pan drippings into your meals creates delightful layers of rich and delicious flavors.
