Simmered Smoked Beefalo Tongue

1 smoked beefalo tongue, 3 to 3 1/2 pounds
1 onion, sliced
1 celery stalk
1 bay leaf
1/2 tsp. black peppercorns

Put tongue in kettle and cover with water. Add remaining ingredients and bring to boil. Cover and simmer 3 to 3 1/2 hours, or until tongue is tender. Remove tongue, pull off skin, trim and remove bones. Chill in the broth (can be done to the point the day before); cut into thin slices.
