01 -  In a wide skillet or shallow saucepan, add milk, bay leaf, peppercorns, and garlic. Bring to a gentle simmer over medium heat. 
 02 -  Add smoked haddock fillets in a single layer. Cover and gently poach for 8–10 minutes until fish flakes easily. Remove fish with a slotted spatula and keep warm. 
 03 -  Strain and discard solids from the poaching milk (optional: reserve a few tablespoons for sauce). 
 04 -  In a small saucepan, melt butter over low heat. Stir in lemon juice, zest, parsley, and a touch of reserved poaching milk if desired. Season with salt and pepper. 
 05 -  Plate fish and spoon warm lemon-butter sauce over the top. Serve with potatoes and greens.
