Large heavy-based pan
Wooden spoon
Fine sieve
Slotted spoon
- 2 smoked haddock fillets boneless
- water enough to cover the haddock
- 1 onion chopped
- 600 ml full fat milk
- 450 g potatoes (1 lb) boiled
- 25 g butter (1 oz)
- 1 g salt
- pepper to taste
Skin the haddock if necessary and place it in a pan with enough boiling water to just cover it. Add the chopped onion and bouquet garni (if using). Bring to a boil, then reduce the heat and simmer gently for about 10-15 minutes until the haddock is cooked.
Once the haddock is cooked, carefully remove it from the pan and set it aside. Strain the stock through a fine sieve and return the stock to the pan. Flake the fish, making sure to check for any remaining bones, and return it to the stock.
In a separate pan, bring the milk to a boil, then add it to the stock. Simmer the mixture for a few minutes to allow the flavors to meld together.
Meanwhile, mash the potatoes with vegetable fat spread until smooth. Add the mashed potatoes to the pan with the stock and stir to thicken the soup to a desired consistency.
Season the soup with salt and pepper according to taste.
Optionally, ladle the soup into warmed bowls, garnish with chopped chives or parsley if desired, and serve hot.
