It is easy to make soup stock though a little messy and time intense. Place the water in a large stock pot and bring to a boil. Add the stock vegetables and simmer for 3 hour. From time to time skim off the scum that will come to the top.
Remove from the heat and with a slotted spoon remove the bones and the stock vegetables and discard. Transfer the stock to another stock pot or large bowl, sieving the stock to remove any remaining solids.
To make the soup
Prepare the vegetables by peeling, washing and chopping the potatoes, celery, onion carrots, rutabaga and leek.
Add the stock, seasoning and bay leaf. Bring gently to the boil then reduce the heat to simmer for about an hour. Remove the bay leaf. Test to see if done by forking the potatoes and carrots. They should be quite soft but not mushy.
Gently mash the mixture, leaving a few lumps of potato and carrot.
Serve and garnish with the parsley or chives and enjoy the tattie soup with your favorite bread.
