Meaty and flavorful
I ate these straight from the tin at room temperature, sometimes sopping up the extra liquid with decent bread.
I purchased these because I wanted to try an alternative to the King Oscar. I've tried a couple different kinds of mackerel over the years, and while the King Oscar has been the best I find their olive oil varieties to be a bit acrid.
Not so with these Otter Kingdom fillets. Theses are actual fillets, so they are larger and meatier, and in my experience they have a looser grain than the mackerel I'm used to. They are high-quality, so I'm not detecting any bones and there's no formaldehyde-flavor, no imperfections in the cut. The oil is quite thin/watery and fairly small in volume. This isn't an issue for me, if anything I'd say it's welcome as it doesn't overpower the fish.
These make a great compliment to my tinned fish rotation, which includes tuna, squid/octopus, sardines, cod liver, oysters, and sometimes sprats, salmon, and trout. The price is better than King Oscar, so I can have it more regularly without feeling like I'm being immoderate.
Would recommend.

Excellent quality, but close to expiry date
I am basically repeating what another reviewer said in 2024, that the quality of these mackerel fillets is excellent except the expiry date of the case I received is only 6 months away, whereas similar products are shipping with expiry dates 4 years away. And my review comes 2 years after the one in 2024, so apparently this has not changed. Otherwise, I would definitely have given 5 stars. Regardless, I went ahead and ordered more, because that is how tasty they are and selling at a good price.

Delicious, healthy lunches!
Really tasty mackerel. I concur with other reviewers, it's a healthy slab of fish I like to drop on a bed of crushed corn chips, fork-flake it and chow down. Better than just about any other off the shelf grocery store brand.
