Gravy That Will Keep a Week

Ingredients

Directions

Cut the lean beef into thin slices.
Place the beef in a frying pan without any butter or fat.
Cover and cook on low heat until the meat's juices are absorbed back into it, shaking occasionally.
Add enough water to cover the meat and let it simmer until reduced.
Add a small amount of water, herbs, onions, spice, and a bit of lean ham.
Simmer until the gravy is rich, then store in a cool place.
