Soup Maker: Scottish Cullen Skink Soup Recipe

I’ve seen lots of different recipes that say they’re Cullen Skink, but the traditional way is to use smoked haddock, onions and mashed potatoes.  Using the traditional Cullen Skink Recipe requirement of pre cooked and mashed potatoes wasn’t an option for the slow cooker, as I wanted to be able to add the potatoes to cook in the pot like the other soup maker recipes.

I used regular haddock rather than smoked haddock, as I’m not a smoked fish fan.  If I’d used the smoked haddock, then I wouldn’t have eaten it.  Smoked fish is a very niche taste, with a smaller potential base of people who would enjoy it, so change your ingredients to suit your own tastes.

Using the water from the poached fish as the fish stock for your soup is what makes the dish.  Without it, the taste will be diluted and it will simply taste of heated milk.

In the end, I had a wee bit of a disaster when my soupmaker gave up the ghost half way through and shorted out.  It meant I had to transfer it to a pan to finish the job for this recipe, but it still turned out very nice.    To serve, I simply dolloped in some mashed potatoes made for the supper that evening, with a dash of parsley on the top.

Presentation wise, this is a lovely soup to dish up.  It would look perfect on any dinner table with some decoration on top of the actual soup itself.  A piece of cooked fish would also work really well sat on top of the mashed potatoes.  This is more of a meal in a plate than a regular soup, so be ready to have a full stomach after only one bowl full.

This is my version.  How would you make yours?
