1In a small saucepan, heat clam juice and peeled potatoes. Bring water to a boil and let simmer until tender, about 15 minutes.
2Place bacon in a large stock pot. Cook over medium high heat until evenly brown. Stir in onions and celery. Cook until vegetables are soft.
3Add potatoes, clam juice and clams to the stock pot. Heat until simmering.
4In a separate pot, gently warm (do not boil) half and half. Pour warm half and half into the stock pot and heat just until warmed through. Do not boil the chowder or the cream will separate. Serve hot.
