These Maria Organic Mackerel Fillets with Organic Piri-Piri came from Caputo's a few weeks ago. It's been a while since I cracked open a can of mackerel, and I also wanted to compare this one to some from Minerva I had about six weeks ago.


Initial impression upon opening the can: 5/5.
Some really pristine looking mackerel fillets. I don't see any piri-piri pepper (yet), and the oil is a greenish gold rather than the expected tinge of red from the pepper. The aroma isn't revealing anything about the fish or the seasoning. A sip of the oil is similarly ambiguous.
Let's See What We Have Here

There are three hefty fillets. Each pulled from the tin intact. And there's the lone piri-piri pepper. (That Minerva I had before was spiced with the traditional pickle, carrot and pepper.)
A substantial amount of oil remained in the deep can. It's organic EVOO, and not wanting to let it go to waste, I poured it all over everything. Initially perhaps a bit of overkill, but in retrospect not.
The meat is firm but tender and flakes readily. The flavor is mild with only a very slight "tang". The salt level is enough to be complementary without being obtrusive. I'm ambivalent about experimenting with any condiments, but ultimately decide against it.
The thing that's lacking, though, is any real input from the piri-piri. In some cases, one lone pepper can really fire things up; in others two or three might do nothing. I don't suppose the heat potential of any pepper can be realistically assessed in the canning process.
I finished the fish, then ate the pepper, seeds and all. No flavor to it whatsoever. Fortunately, the mackerel stood on its own quite well, so the disappointment over the spiciness was minimal.
Main Takeaways
- Beautiful mackerel fillets
- High quality organic EVOO
- Piri-piri spice MIA
Breaking down the carton for archiving, I noticed the date stamp indicated it was packaged December 2023. I was a bit surprised this can purchased in January 2026 had taken that long to sell.
