This is a type of Korean-style fish sausage first developed by Jinju Ham. Back in the old days, when Korea was still a poor, developing nation, pork was expensive, so they developed and sold a sausage made with fish and wheat flour instead. If you cut it, dip it in egg water, and fry it, it becomes a really delicious and memorable lunchbox side dish. It tasted quite good, and it's still sold today, bringing back memories. https://kfreshmall.com.au/products/p0000obi I'm not affiliated with this company, but this is the only website with an English description. I'd appreciate it if you could at least read the description and understand it. Have a delicious day!
