Just like mum's but minus the traditional "scrunchions" (salt pork fat) so you can eat them more often!! If you can't get salt cod in your area, try another salted or corned white fish
Soak salt cod overnight or for 8 hours. Prep your veg during this time.
Drain the fish and add fresh water, then boil for 10 minutes.
In a separate pot, boil your potatoes until fork tender (about 20 minutes), drain and mash.
Add the onion and the fish, season with pepper, and stir all together, being sure to flake your fish well.
Once cooled to the touch, form 1/4 thick patties with your hands, using roughly 1/4 cup mixture per patty. You should get 16-18 patties.
Heat your butter and oil in a cast iron skillet or non-stick pan over medium heat (for more crispy edges and more even browning, go with the cast iron - just beware you may need more oil).
Fry the fishcakes in batches for 2-3 minutes per side or until golden brown. Serve warm with mustard pickles and salad greens on the side for a nice little lunch :)
