My most recent obsession
Size: 3 Ounce (Pack of 4), Size: 3 Ounce (Pack of 4)
The best canned oysters I've had yet! Theses oysters taste very fresh and clean, no crunchy bits like the cheaper ones. They're perfectly soft and melt in your mouth. I like eating them straight out the can but I also like mixing them with mayo, some of the olive oil from the can, some crushed pepper and eating them on baguette slices. These are so good my brother has started stealing them from me. I'm gonna have to start hiding them.

Great Tinned Oysters from South Korea No seed oils !!
Size: 3 Ounce (Pack of 12)
Great canned smoked oysters- the smoke flavor was very strong in the can I used to make faux Oysters Rockefeller. Next time I will drain them a little more and add a few drops of lemon or vinegar.
There were 9 plump oysters carefully packed in olive oil in the first can opened and it made a great meal.
I opened another can the next day and drained it well. adding a few drops of vinegar The second can's flavor was balanced, smokey and delicious.
Online there are many recipe ideas incorporating these delicious oysters.
These appear to be a superior quality of canned seafood from South Korean fisheries and in my opinion there are none of the known food safety issues which are my concern when dealing with the admittedly less expensive (half the price) brands from the other asian fisheries.
I consider these a good value due to advertised no industrial seed oils and the quality of the oysters.
4 stars due to the cost/ 5 stars for taste
