I bought six cans of salmon from Aldi. I was short on time and money, but wanted fish. I'd had canned salmon before, from other stores, and it resembled canned chicken, cut into cubes.
When I opened the first can I had to slap it a few times for the jelly to loosen and ooze out. It plopped on my table and retained its shape. It smelled like cheap dog food. If I didn't eat it, I'd go hungry until lunch the next day. So in I dug.
I described it later as "eating a crime scene," and I hold to that. It was as if someone had taken a whole fish, skin and bones and all, and forced it into a can until it fit. It tasted like several things, none of them salmon.
To this day I don't know if it was actually human food. Either way, I would up throwing out the other cans after being refused a refund.
RIP canned flesh, whatever you were.
