The Costco fish is packed in a 4% salt solution
The Washington Post recently provided a top chef with a variety of wild and farmed salmon, ranging in price from $6/lb. to $20/lb., and had him prepare dishes for a table of food-snob judges. In the end, farmed salmon handily defeated the wild stuff and the Post concluded that you don’t always get what you pay for.
Judging each salmon on a scale of 1-10, the cheapo Costco fish scored the highest at 7.6. Costco also had the lowest-scoring fish on the test, as the wild coho brought up the rear with a mere 3.9 out of 10.
