And funnily enough, it's not even its flavour (at least not on its own) that would win you over. It's what happens when you dribble a little fish sauce into stir-fries, curries, marinades, even salad dressings. Suddenly, your dish takes on a depth of flavour you hadn't previously detected, a complexity that you can't quite put your finger on, a strong punch of meatiness without tasting meaty.
And that pungent aroma? You won't be able to detect it. But you won't want to go without this precious bottle of fish sauce again.
It's a rather ego-less ingredient in that way; fish sauce is not at its best on its own. But my, what a team player. And it's that ability, to transform its fellow co-habitants into something better than they were before, that has won the hearts of cooks throughout Southeast Asia, from Thailand and Vietnam to Indonesia.
It's incredible what just two ingredients, anchovies and salt — the building blocks of fish sauce — can transform into when left to their own devices for a few months. Indeed, this kind of fish sauce is actually related to modern day Worcestershire sauce, which also is a fermented anchovy-based sauce.
Use it as you would soy sauce, to amp up the umami-ness of whatever you happen to be whipping up for dinner. Just one hint: Balance out all that saltiness with just a dash of brown sugar and a good squeeze of lime juice, as I do in my Vietnamese-style skirt steak. You don't have to make an Asian-style marinade either. I've made a great one using fish sauce, balsamic vinegar, honey and garlic.
VIETNAMESE-STYLE SKIRT STEAK WITH ASPARAGUS AND SCALLIONS
You'll find fish sauce in the Asian or international section of just about any grocer.
Start to finish: 45 minutes (20 minutes active)
3 tablespoons fish sauce
1/4 cup lime juice
1 teaspoon minced garlic
1 teaspoon minced ginger
2 teaspoons brown sugar
1 pound skirt steak
1 large bunch thin asparagus, trimmed
2 bunches scallions, bottoms trimmed
Sunflower or canola oil
Kosher salt and ground black pepper
In a large zip-close plastic bag, mix together the fish sauce, lime juice, garlic, ginger and brown sugar. Taste for seasoning, adding more sugar or lime juice if the marinade is too salty. Place the skirt steak in the marinade, making sure it's well covered. Seal the bag and set aside on the counter for 30 minutes.
Meanwhile, prepare a grill for direct medium-high heat.
Toss the asparagus and scallions with a little sunflower oil, salt and pepper. Set aside. After 30 minutes, remove the steak from the marinade and place on a paper towel-lined plate to remove excess marinade.
Using an oil-soaked paper towel held with tongs, oil the grill grates. Set the steak on the grill and cook for 3 minutes, depending on the thickness of the meat, until a good charred crust develops on the underside. Flip and cook for another 2 minutes, or until a meat thermometer inserted into the thickest part of the meat registers 125 F. Transfer the steak to a warm plate, tent lightly with foil and allow to rest 5 to 10 minutes.
Meanwhile, place the asparagus and scallions on the grill and cook the scallions for 2 to 3 minutes, or until slightly wilted, and the asparagus for 5 to 7 minutes, or until very lightly browned.
Slice the steak across the grain and serve over the grilled vegetables, with a fresh squeeze of lime juice, if desired.
