Sauté the Vegetables
In a large pot, melt the butter over medium heat. Add the chopped onion, celery, and carrot. Cook, stirring occasionally, until the vegetables are soft and fragrant—about 5 minutes.
Simmer the Potatoes
Add the cubed potatoes, seafood stock, and bay leaf to the pot. Bring to a boil, then reduce the heat and let it simmer gently for about 10 minutes, or until the potatoes are fork-tender.
Stir in the Dairy
Reduce the heat to low. Stir in the milk and heavy cream. Warm the mixture gently—do not allow it to boil. Simmer for another 5 minutes to allow the flavors to blend.
Add the Seafood
Gently fold in the lobster meat, shrimp, scallops, and cubed white fish. Continue to cook over low heat for 4 to 6 minutes, just until the seafood is fully cooked and opaque. Season with salt, pepper, and smoked paprika (if using).
Garnish and Serve
Remove the bay leaf before serving. Ladle the chowder into bowls and garnish with fresh parsley or chives. Serve hot with crusty bread or traditional tea biscuits on the side
