You take and clean 1 elephant; skin, gut, remove feet and head. Dispose of all.
Cut meat into stew sized cuts, keeping the bones as they provide good broth, salt and pepper, and brown in a pan.
After browning place into a large pot.
Clean and dice ~ 2,000 lbs of mixed vegetables, add to pot. (Skip the turnips)
Fill pot with water to cover stew: ~ 1000 gallons of water.
Bring to a low boil for 10 hours and then lower heat to medium and cook covered for 48 hours.
This will serve 2,500 friends.
If you are expecting additional guests, you could add 1 or 2 rabbits. Careful to not add more as most people do not like hare in their stew.
Tried and true. Quite yummy actually.
