If green peanuts are not in season, use raw unshelled peanuts in bags found in the produce section. An alternate choice but when boiled will produce goobers just as good.
If you don't have 2 days, cook on high heat for 4 hours, then reduced heat to low, stir and add more hot water if needed and cook overnight or about 10 hours. Let set for an hour or so to soak in all the seasoned water. This later method will produce a firmer goober.
