I think you can get them generally across much of Yorkshire, but outside of that it's a freak occurrence and to be praised and treasured if/when you come across a proper fishcake. I feel strongly about this.
Fishcakes? They're mostly deep-fried disappointment since they're not proper Sheffield fishcakes.
Last year, the company I work for had a 'mental health' day. I used it to drive a 280-mile round trip to Sheffield just to go to Two Steps chippy on Sharrow Vale Road for a fishcake butty for lunch. Fucking worth it. Absolutely.
Fishcake tends to be flaked fish mixed with a starchy ingredient (usually potato mash) that's given a crispy coating. You'll find minced cheap fish and potato used on the cheaper varieties.
So, a fillet of fish, sandwiched between potato slices and covered in a crispy batter, isn't a million miles away from the traditional fish cake.
Yep, whole childhood a lie I'm afraid. Fish cake is usually mashed potato mixed with fish, fried (usually breaded).
Although that said, has anyone ever encountered a cod roe "fish cake"? Literally a slice of pressed roe fried up. So I guess "fish cake" covers a multitude of sins.
The strange breaded minced up fish things are usually called fish sticks in America. Kids love them.
Meanwhile the only place I’ve encountered “fish cake” is at Japanese ramen restaurants where its this weird slice of fishy tasting something they put on the Ramen. Found it here:
Cooked flaked, salted cod fish stirred into a potato mash with a little savory, salt and pepper. Make them into rounded balls just smaller than tennis balls. Hot iron skillet and a little butter. Pop them in the pan and press em down with the spatula until they're about an inch thick. Do both sides until golden brown and warm through and you have what I consider a fish cake.
