If using fresh clams, steam them in a little water until they open, then remove the meat and reserve the strained liquid.
Fry the bacon in a heavy pot until crisp, then add the onion and celery and soften for 5 minutes.
Stir in the flour and cook for 1 minute, then gradually whisk in the reserved clam juice and 300 ml water.
Add the potatoes and bay leaf, bring to a simmer and cook until the potatoes are tender, about 15 minutes.
Pour in the milk and cream, add the chopped clams and heat gently without boiling for 3 to 4 minutes.
Season with salt and pepper, remove the bay leaf and serve with crackers or crusty bread.
