Warm a glug of olive oil in a pan. Add the leek, celery and garlic. Season. Fry for5 mins over a medium heat till the veg is soft and glossy.
Pop the potatoes into the pan. Give everything a good stir. Fill the kettle and boil it.
Pour in 500ml of hot water from the kettle. Stir and cover. Let the chowder bubble for 10 mins. The potatoes should be nice and soft.
Turn the heat right down. Add the salmon. Pour in the milk. Give the chowder a stir. Let it warm through. Don’t let it bubble. You just want to gently warm the milk and salmon.
Stir in most of the parsley. Taste. Adjust the seasoning if you think it needs it. Ladle into warm bowls. Top with the last of the parsley to serve.
