When I was researching for last week’s salsa post, I came across references to one of the earliest known forms of salsa, namely Garum, the pungent roman fish sauce. Then a friend posted a note about discovering that some kimchi she ate had shrimp in it, which she’s allergic to, (traditionally, it usually does include shrimp). That prompted a question about using fish sauce instead of shrimp in a kimchi recipe, (perfectly fine), and the fact that not all fish sauces are created equally. Then, a bit later, M and I were discussing that, when she noted that “proper use of fish sauce dictates that you shouldn’t taste it, (pretty much true, that), and, well – After all that I figured I’d better write about fish sauce.
While it’s enjoyed somewhat of a resurgence in recent years, fish sauce is still not all that common in most kitchens, especially here in the U.S. Why that is becomes immediately evident when you open a bottle and take a deep whiff – Fish sauce is definitely funky – Yet the undeniable fact is this – If you’re looking for that certain je ne sais quoi to add salty and umami to a dish, fish sauce is the thing to reach for. And if that’s so, why did it die for so long? The answers are twofold – One, because of the fall of the Roman Empire, and two, fact is, it didn’t – It’s been alive and thriving in Asian cuisine, especially Vietnamese, for thousands of years.
It’s a reasonable assumption that humans have been saucing things since well into prehistory. Once we hit some form of civilization, that tendency multiplied in spades. Arguably no society has been more attuned to that trend than the Romans were. Roman chefs and diners seemed to disdain any food in its natural form – Everything had to be tweaked, poked and prodded into something else, and all of it was heavily sauced.
While the Roman Empire afforded its wealthy the chance to enjoy food, herbs, and spices from around the known world, the one thing that fueled everything was salt. It’s arguable that salt was in fact a tap root of their economy, as well as the key to their culinary hearts. In almost every place the Romans conquered, they looked for salt – in mines, evaporation projects, and boilers. Often enough, what they conquered was taken because of salt, because while the Romans traded in damn near everything, salt was simply a thing they couldn’t do without. First and foremost, it was a critical part of feeding and supplying the Roman Legions. Men and animals needed it to survive, let alone fight. It was also a huge part of what kept the lowly masses at bay – As long as they had salt and olives, and maybe a little bread, they were more or less quiescent, and that was critical for the ruling class to be able to remain thus.
Back to those sauces – What ruled back then, hands down, was fish sauce. It was in almost everything they ate, from Senator to plebeian. Now, that’s not to say that all fish sauce was created equally – Just as today some drink Veuve Clicquot and others Cooks, there was a wide variety of quality and price when it came to fish sauces. At the top of the heap was Garum, a relatively clear sauce made from the guts and gills of mackerel. This stuff was used at table, and could be fabulously expensive – The creme de la creme was called Garum Sociorum – It was made in Spain, and cost as much as an average Roman Legionnaire got paid in a year, so it doesn’t take a rocket scientist to figure out who got it and who didn’t. Next down the chain was Liquamen, basically, a sauce made in a manner quite close to the way it’s still done throughout Asia – The whole fish was salted and fermented, and a sauce was pressed from that after sufficient processing time. That was used by the cooks, and replaced salt in the vast majority of Roman dishes. Further down the chain came Muria, which as far as we could tell, would be the mixed dregs of the various higher cost fish sauces, pressed – and finally came Alec, which was literally a paste made from the sludge gleaned from cleaning a garum or liquamen making facility – Obviously, the plebeians got those last two products at their tables.
Fish sauces were so key to Roman life that production facilities were made anywhere and everywhere they could be. On the Italian peninsula, in Spain, North Africa, the Middle East, and even Europe and Great Britain, fish were set out in the sun, (basically, to almost get on toward rotting somewhat), and then fermented into the various sauces. It must have been a distinctly pungent experience, to say the least. There was even a certified Kosher version made in occupied Israel.
As fate would have it, in the late 5th Century, the German conqueror Odoacer became the first barbarian ruler of Rome, and the empire was a thing of the past. Along with the fall of the rulers came the fall of all that fish sauce processing – Turns out the Germans didn’t care for the stuff – So a huge network of cottage industries surrounding the production of fish sauce vanished in a relative heartbeat – Except that it didn’t.
It’s not a stone cold fact that the Romans made it to Vietnam, but they probably did. Ptolemy mentioned the garrison of Cattigara, which is likely Óc Eo, in modern day Vietnam. Roman artifacts have been found there, as well as throughout Southeast Asia – No surprise, given the depth and breadth of Roman conquest and trading practices. And it’s there, in Vietnam, and eventually throughout Asia, that fish sauce was firmly established and has remained in steady production. Whether it’s Núoc Mám in Vietnam, (among other variants, they make it out of everything else too – crab, squid, shrimp, you name it), Nam Pla in Thailand, (there’s over 200 different makers there), or Bagoong in the Philippines, it’s a sauce made by fermenting little fish, (usually something from the Herring or Sardine family), and letting them sit for months – The result is as popular as it was to the Romans, and they’ve been making it continuously for thousands of years.
And now to throw another wrench into the works – It turns out that the process and the sauce never completely left Italy after all – and the differences between what’s found there now and what’s found throughout Southeast Asia are profound and illuminating. In my pantry is a little round bottle labeled Colatura di Alici di Cetara. The contents are gorgeous, a rich amber liquid, obviously quite viscous. Open the stopper and wham! It is seriously fishy, funky and potent as the day is long. It’s not an acquired taste – You either dig this stuff or you don’t. Cetara is a little fishing village tucked into the coast of Campania, between Amalfi and Salerno. There, back in the Middle Ages, a bunch of local monks somehow rediscovered the recipe and process for liquamen and started producing it again, and the town has been doing so more or less every since. It’s made from anchovies caught between March and July, then barrel brined and aged until the late fall, when the precious stuff is pressed and bottled. This is as close to the real deal as you’ll ever get today – This is the stuff Roman cooks used to add salt and umami, (whether they knew it or not), to so many ancient dishes – And that’s the best way to use Colatura as well.
Back in Vietnam, what they produce is a far cry from Colatura. There, I’ll boldly call the pinnacle of the art the sauce produced by Red Boat Fish Sauce. Find yourself a bottle of Red Boat 40° N, and you’ll be good to go. This is made from black anchovies from the Phu Quoc archipelago, and salt – That’s it. They’ve been making it the same way for hundreds of years, and it shows. Open that bottle and you get a much more nuanced presentation than Colatura – A gentle caress of your cheek, as opposed to an open handed slap. The fish and funk are still there, but much subtler, and there are other overtones as well, hints of Asia and the smell of Vietnamese cooking. To me, Red Boat is the Garum of our time – I’ll happily sprinkle a little out of the bottle onto whatever I’m having, and it’s awesomely good.
Get yourself a bottle of each of the above, and you’re good to go for all your fish sauce needs. But, before we talk about what to do with them, let me say this about the general state of the fish sauce nation – Having made a resurgence in the culinary world, there are a boatload of products out there. Just like badly prepared calimari, folks who say they hate fish sauce have, nine times out of ten, had crappy fish sauce – God knows there’s enough of that for sale. Let me save you much strife – Most of what you find in the average grocery store is crap. You have no idea what fish they’re talking about, and they sure ain’t tellin’ – At worst, this stuff is truly nasty, and at best, it’s insipid – Avoid it all like the plague and go with my recommendations.
As for what to do? Well, that’s easy – Replace salt with a drop or two of Colatura in damn near anything, and you’ll get not only the Salt note you’re looking for, but a hint of something deeper. Same goes for Red Boat. Used properly, aka very sparingly, you’ll get wonderful, subtle notes without any fishiness whatsoever. An on that note, I refer back to M, who’s comments came following a visit to Vietnamese joint in Seattle that overdid the fish sauce on whatever it was she ordered – The rule is hard, fast, and simple – If it tastes like fish sauce, you used too much. Chances are real good, you won’t make that mistake twice.
