Mix 1 1/2 cup of drippings and 2 cups of water or 3 cups of store bought broth with any herbs or other seasonings (1 tsp. dried herbs like rosemary, parsley or sage work great here) you'd like use over medium-high heat
Meanwhile, combine 3 T cornstarch with 1/2 C water or store bought broth
Whisk well with a mini whisk or fork until smooth and completely combined
Once the drippings and water or store bought broth you are cooking over medium-low heat begin to boil, slowly pour in the cornstarch mixture whisking continually
Turn heat to medium and continue whisking, a little slower now, until the gravy starts to thicken
Season with salt and pepper to your liking then remove from heat and pour into your gravy boat. You are all ready to serve!
