Cut steak into smaller portions (to fit size of biscuits).
Salt and Pepper each side Dredge in flour Put enough oil in fry pan to come up to about 1/4 inch Fry steaks on med hi heat until browned on both sides.
Put browned steaks in crock pot, add beef stock (may need to add a little more water to cover completely).
Cook on low heat for 12 to 18 hours.
If you use beef stock or water instead of gravy, the liquid after some hours of cooking may need to be poured into a sauce pan and thickened with about 2 tablespoons of flour if you want gravy, then you can add it all back to the pot to cook for the rest of the duration.
Serve in your favorite biscuits or over rice or mashed potatoes if you want to make them for a supper meal.
