Here is a simple recipe for making Fish Chowder:

Ingredients:

• 1 lb. fish fillets (such as cod, haddock or halibut)
• 1 large onion, diced
• 2 cloves of garlic, minced
• 2 cups of diced potatoes
• 2 cups of milk
• 1 cup of fish stock or chicken stock
• 2 tbsp butter
• 2 tbsp flour
• 1 tsp dried thyme
• Salt and pepper to taste
• Chopped parsley for garnish (optional)

Instructions:

1. In a large pot or Dutch oven, melt the butter over medium heat. Add the onion and garlic, and cook until softened.
2. Stir in the flour, thyme, salt and pepper, and cook for another minute.
3. Gradually add the fish stock or chicken stock, stirring constantly. Bring the mixture to a simmer and add the diced potatoes.
4. Reduce the heat to low and let the potatoes cook for about 10 minutes, or until they are tender.
5. Add the fish fillets and milk to the pot. Bring the chowder back to a simmer and cook for about 5-7 minutes or until the fish is cooked through.
6. Taste the chowder and adjust the seasoning as needed.
7. Ladle the chowder into bowls, and garnish with chopped parsley (if desired).
8. Serve with a crusty bread or crackers.

You can use different types of fish, such as cod, haddock, or halibut, depending on your preference. You can also add other ingredients such as carrots, celery, or corn. The key to this recipe is to use fresh ingredients and cook everything at a low heat to keep the flavors of the ingredients at their best.
