Fish Sauce

We gathered five products from grocery stores and Asian markets and sampled them over white rice, mixed into a simple Thai dipping sauce, and in our recipe for Vietnamese Caramel Chicken.

UpdateApril 2016
We recently discovered that Thai Kitchen Premium Fish Sauce has been reformulated. It now specifies that it's made with sea salt and lists water as an ingredient, but it contains the same amount of sodium per serving. After tasting the new version, we still recommend it.

What We Learned

What is Fish Sauce?

To the uninitiated, fish sauce might seem like an odd concept. Like soy sauce, it’s both a condiment and an ingredient, and it’s full of glutamates that enhance flavor in food. But while soy sauce is made from comparatively mild-tasting fermented soybeans and grains, fish sauce gets its signature flavor from something far more potent: fermented anchovies. Manufacturing methods vary among producers, but the basic process is the same: Fresh, whole anchovies are layered with sea salt and left to ferment in vats for at least 12 months. Over time, the fish breaks down and the salty liquid that forms is collected and filtered before bottling. It’s strong stuff with an intense aroma. But there’s a reason that this pungent sauce is a critical component of many Asian cuisines and is becoming increasingly commonplace in American kitchens. It boasts a rich, savory taste and a brininess that brings out depth and flavor in everything from dipping sauces and soups to stir-fries and marinades.

How We Tasted Fish Sauce

When we last tasted fish sauce, we deemed all six brands in our lineup acceptable. But recently, when we developed a recipe for chicken braised in a fish sauce–spiked caramel sauce, we noticed significant variations in saltiness and quality among brands. An update was in order. We gathered five products from grocery stores and Asian markets and sampled them over white rice, mixed into a simple Thai dipping sauce, and in our Cook's Illustrated recipe for Vietnamese Caramel Chicken.

Look For Higher Protein Content

Every brand was intensely flavored, but the best of these balanced saltiness with a complex, savory taste. Less successful brands were either overwhelmingly salty or unpleasantly “fishy.” Two brands listed “anchovy extract” instead of “anchovy” on their ingredient lists, but one was near the top of our rankings and one at the bottom, so we discounted it as a significant factor. What did turn out to be key was protein content. An independent lab confirmed that our winner contained nearly double or even triple the protein of the other products in our lineup: 20.58 percent protein by weight, compared with 11.44 percent for our runner-up and 7.44 to 8.92 percent for the remaining products. Though this sauce also had the highest sodium level, its abundance of protein kept it from tasting overly salty. Moreover, the other products tended to taste saltier, even though they actually had less sodium than our winner. This sauce was also the only one that didn’t contain sugar.

The Best Fish Sauce

Our new favorite is the second most expensive option in the lineup, but we think its “rich, m...

Absolutely the best chicken ever, even the breast meat was moist! It's the only way I'll cook a whole chicken again. Simple, easy, quick, no mess - perfect every time. I've used both stainless steel and cast iron pans. great and easy technique for “roasted” chicken. I will say there were no pan juices, just fat in the skillet. Will add to the recipe rotation. Good for family and company dinners too. I've done this using a rimmed sheet pan instead of a skillet and put veggies and potatoes around the chicken for a one-pan meal. Broccoli gets nicely browned and yummy!

Amazed this recipe works out as well as it does. Would not have thought that the amount of time under the broiler would have produced a very juicy and favorable chicken with a very crispy crust. Used my 12" Lodge Cast Iron skillet (which can withstand 1000 degree temps to respond to those who wondered if it would work) and it turned out great. A "make again" as my family rates things. This is a great recipe, and I will definitely make it again. My butcher gladly butterflied the chicken for me, therefore I found it to be a fast and easy prep. I used my cast iron skillet- marvellous!

John, wasn't it just amazing chicken? So much better than your typical oven baked chicken and on par if not better than gas or even charcoal grilled. It gets that smokey charcoal tasted and overnight koshering definitely helps, something I do when time permits. First-time I've pierced a whole chicken minus the times I make jerk chicken on the grill. Yup, the cast iron was not an issue.
