All About Fish Sauce

The anchovy is not a universally loved fish. In fact, that may be understating the matter. A lot of people hate the pungent, bottom-of-the-ocean flavor of anchovies, and they're very vocal about it. The very suggestion of anchovies on a pizza may make them dump the Italian take-out menu and switch to Chinese instead.

Of course, people who love anchovies are often just as passionately outspoken. The humble anchovy is food that divides a room. I find myself in the odd position of having crossed from one side to the other, and all because of a sauce. I used to hate anchovies, but I'm a convert, thanks to fish sauce.

Actually, my conversion started with Worcestershire sauce, that divine savory liquor of vinegar, tamarind, and, yes, anchovy. As a lad, I liked to put Worcestershire sauce on almost everything, from shepherd's pie to cheese on toast. I had no idea that it contained the hated anchovy, and my world almost fell apart when I discovered the terrible truth, cunningly hidden in plain sight on the ingredients on the back of the label.

I didn't give up Worcestershire sauce, but I also didn't rethink my position on anchovies. It was only when I tried to make my first Thai green curry that I really had to give the matter serious thought.

Thai cooking relies heavily on fish sauce, as do the cuisines of Vietnam, Indonesia and southern China. Called nam pla in Thai, fish sauce is the seasoning that provides much of the saltiness in Thai recipes. It also has a very short ingredients list. It's essentially just anchovies and salt. It can be made with other fish, but it's unusual. On a visit to my local Asian supermarket I saw bottles labeled with pictures of squid, crab, and whole cornucopias of aquatic life, but they all contained the same ingredients: anchovies and salt.

Nam pla is made by layering those two ingredients in big barrels and leaving it to ferment under the hot sun over the course of several months. The anchovies break down in their own juices, and the resulting liquid is extracted, filtered, sweetened with a little sugar, and bottled.
