Red Boat 40°N Fish Sauce
I use fish sauce a lot. A big bottle will last me 3-5 months and I've always used 3 Crabs brand. I'd heard some good things about Red Boat 40°N being "first pressed virgin," only containing salt and anchovies, having a higher Nitrogen content, etc. but being over 3x the price of my usual for a smaller bottle (At Whole Foods, where everything's more expensive than it needs to be) I was on the fence. Then yesterday I went into my usual Vietnamese grocer and there it was for only a couple bucks more than my usual fish sauce so I had to see what all the fuss was about with it.
Oh man was I missing some good fish sauce. Night and day difference in flavor, complexity, the whole nine yards. Blows away Lucky, 3 Crabs, Tiparos, Squid, etc. I'm officially a convert and Red Boat 40°N gets the No Mayo Stamp of Approval (NMSA®). If any of you cook SE Asian dishes on a regular basis I'd recommend tracking some of this stuff down and trying it.
