Leftover Mashed Potatoes = Fish Cakes

One of the most popular recipes on my site are my salmon cakes.....they are just so good, it's hard for me to try another type of fish cake.
But I found myself with leftover mashed potatoes (unheard of!), so fish cakes it would be.

Truth be told, I have never made mashed potatoes in my life.
I did not grow up eating them (how sad for me).
My mother was always a health nut so we only had baked potatoes cooked in aluminum foil to accompany that dried out chicken or steak.

But last night, I had leftover mashed from dinner OUT. So they were restaurant good.....lots of cream and butter, you can be sure.
I didn't have the heart to throw them away, so I took them home, ready to give them new purpose.

I poached a piece of salmon (18 minutes in water, bay leaves, peppercorns, fresh dill and lemon slices), so I had some poached salmon, and thought the fish w/ the mashed potatoes sounded like a good combination. Very British, no?

If you don't have poached salmon laying around, then by all means, use a can of good quality pink salmon.

These were yummy....

Here's how:

6 oz. of cooked cold salmon (I used poached)....you could also used canned salmon
1 cup of cooked cold mashed potatoes
1 egg
1 tbsp Dijon mustard
1 tbsp capers
1 tbsp fresh dill, chopped
1/4 cup panko breadcrumbs (to bind)
salt & pepper

Mix all ingredients together in a bowl.

Line a half sheet pan with parchment paper.
Using an ice cream scoop for even patties, scoop portions out onto the baking tray.

Keep in the fridge (at least 1 hour) until ready to cook.
These need to be cold or they will fall apart.

In a heavy non-stick skillet, heat some olive oil and cook the fish cakes 1 minute on each side.

Drain on paper towels and serve.

By all means, make a tartare sauce if you like, but these were delicious on their own.

These freeze well too....wrapped tightly in plastic wrap, then in foil.

This is almost exactly how I make codfish cakes, except I use parsley instead of dill. I actually found the recipe in Canada's Gaspé peninsula, after my husband and son had just come back from a fishing trip with a huge amount of codfish and I didn't know what to do with them. We went to a folklore museum that featured a display of a typical kitchen from decades ago, with a mannikin of a woman dressed in local costume holding a cookbook. So I flipped through the book for codfish recipes and found the codfish cakes I've been making for more than 25 years. Now I need to try it with salmon and dill.

I didn't have capers so I googled a substitute and used lemon juice and fresh ground pepper. These trout cakes were delicious. We will definitely be making them again!!

I made this recipe with leftover halibut several months ago and am going to make them again tomorrow. We topped ours with mango salsa and it was a hit!
