How to Buy Fish Sauce: A guide

If you want to stock your kitchen with the bare minimum for preparing Vietnamese food, start with good quality fish sauce (nuoc mam). How do you judge fish sauce?  Look for a light amber color and the words nhi or thuong hang on the label.

These terms indicate that the condiment came from the first extraction of liquid from the fermented fish, and is of the highest quality. Grades of fish sauces are similar to that of olive oils.  That is, extra virgin olive oil is more flavorful and costlier than virgin olive oil.  This same rule applies to judging different fish sauces.

Also keep in mind that fish sauce is also used in Thai and Filipino cooking, where it tends to be saltier and heavier in flavor.  So, even though Thailand produces most of the fish sauce sold in the U.S., you need to make sure that the condiment you’re buying is made in the ‘Vietnamese’ style.  How to do this?  Look for Vietnamese lettering alongside the Thai script. 

Sometimes, the terms Phu Quoc and Phan Thiet are included on the label to signal a connection with these two famous fish sauce-producing areas in Vietnam. Fish sauce from Vietnam now sometimes use "Hon Phu Quoc" or "Hon Phan Thiet" (see image on left) to indicate that their product came from islands in those regions; hon means islands, and communicates a more authentic Viet condiment (versus a Thai product, which may not be clued in on such linguistic subtleties).

About five years ago, One Pigeon brand from Vietnam offered different grades of fish sauce, using degrees on its labels to reflect how much the nuoc mam has been diluted with water before bottling. For example, "25° dam" means there's 25% fish sauce in the bottle. When I contacted the producer, he said that most fish sauces are 20%. One Pigeon came in several intensities. The higher the degree, the more you paid. That's how it is in Vietnam. Sadly, that fish sauce didn't last in the U.S.

 

If ca com is one of the ingredients, that's an indication that the end product was made from a high quality anchovy native to the waters surrounding the island of Phu Quoc. Though I like Viet Huong’s "Three Crab" brand for its consistently delicate flavor, aroma and color, I often try newer brands. Please note that Three Crabs and Flying Lion are both made by Viet Huong. The former is lighter in flavor than the latter, according to the Chung family that produces it.

 
Some are saltier while others are sweeter. Let your palate be your guide. Depending on where you shop, there may be as many as a dozen brands to choose from.  As price is often a reliable indicator of quality among Asian groceries, select a mid to high priced fish sauce (about $3 to $4 per bottle!). If you buy online, fish sauce will cost a little more.

Hot to shop for fish sauce:

• Shop price -- choose mid to high price.
• Buy glass over plastic bottles as glass indicates a better quality product.
• Look for Vietnamese style fish sauce which is lighter in flavor than Thai nam pla or Filipino patis.
• Fish sauce with an amber-red color is better than dark coffee.
• Reliable brands I stick with: Three Crabs Brand Fish Sauce and Flying Lion; both are made by Viet Huong. Both are sold at Asian markets. If they're not available, use Tiparos Thai Fish Sauce or Thai Kitchen.
  
• Transport fish sauce standing up in your car, lest it leaks a bit; the bottles are seldom well sealed.
  

How to store fish sauce:

• If you use it often, keep it in a dark cupboard.
• If you seldom use it, refrigerate it where it will keep for months.

How to use fish sauce:

• You can always add more but it's harder to take it out of foods.
• I combine fish sauce with salt in cooking foods because the savoriness of fish sauce isn't the same as salt.
• Old school Vietnamese cooks use lower quality fish sauce for cooking and reserve pricier fish sauce for dipping sauces. If you can afford it, and I hope you can, use only the good stuff. Your food will taste consistently good.

Thanks for the useful information! Fish sauce is an essential ingredient in my kitchen! I even use it in many Western dishes (the Romans had a similar fish sauce, so it is not a heresy)...

Cheers,

Rosa

My favorite fish sauce is the one big blue crab brand. The three small crab brand is too salty for my taste.

[Andrea Nguyen]

That's right, Rosa. The Romans had liquamen made from salted anchovies. They used it in desserts too! It's still made in parts of Italy. And, look at all the anchovies used in Italian cooking for great savory depth. It's not a novel idea but rather a resourceful one!

Pho80 -- I'll look for the one big blue crab brand! Thanks for the tip.

[shavedicesundays]

I pretty much use the Three Crabs brand too. Very informative post!

How about a gluten-free version of fish sauce. I have used Three Crabs for years but because of recent dietary restrictions I need to seek out a gluten-free variety. Any ideas??

[Laura Dwight]

I google searched on fish sauce and gluten and came up with a passage from Let's Eat Out!Your Passport to Living Gluten and Allergy Free By Kim Koeller, Robert La France that had some good advice about how to check for gluten in fish sauce. They cautioned that fish sauce processed in Hong Kong should be avoided since the additional processing can mean additives. The section that was quoted was on Thai restaurants and they said that 'top quality' fish sauce is gluten free and named the following good brands Tra Chang, Golden Boy, King Crab, and Squid. There is probably a section on Vietnamese restaurants that names Vietnamese fish sauce but I could only view part of the book. Which I will now buy!

Wow...thanks for the information, I've been struggling with fish sauces for years, never seeming to get the right consistency, color or taste and after searching out the right products...wow! Thanks.

[Thomas Luk]

Can anyone provide detailed information on how to contact the manufacturer of the one pigeon brand fish sauce from Vietnam? much appreciated

[fishing kayak]

Well, quiet frankly i have never heard of fish sauce, i am pretty good at cooking and i am trying some other stuff in my cookings, i think vietnamese food will be next for me.

[kayak fishing]

i think i should try this fish sauce in my cuisine, i think it is pretty healthy since it comes directly from the fish.

[Andrea Nguyen]

Try it out, you'll find it interesting.

[Tammy]

My mother used the Three Crabs brand and so I have to use what my mother used. I have often wanted to try the other brands, but it feels so wrong! Years of my life with food influenced by that brand... how can I switch? :)

[Andrea Nguyen]

Three Crabs is good, but the Viet Huong company makes several brands that quite good. Go for price.

[Thanh Viet]

Hi Andrea,

last month when I was in Hanoi, I took a picture at Intimex for you... They had 55% Nuoc Mam... posted it on your Facebook page.

[Andrea Nguyen]

Thanks, Thanh Viet! I'll check it out.

I looked at all the glasses, but none seem to match your description.
(Your description was very good, by the way - I understood it!) :-)

If you can't locate the ones you want, you could try contacting the
company Okki Fashion Eyewear

I am using Lindane to get rid of pubic lice. This is a powerful,
expensive, prescription poison. I have found that the lice do not die
immediately upon contact. none of the web stuff i read supports this.
they say remove dead lice after use. I did follow the directions,
exactly.

wher I can buy vietnamese sauces,like nouc mam and others???

[mesa thai food]

I have a large bottle of fish sauce (about the size of a wine bottle) and at the rate that I use it I will probably be able to will it to my children and I'm not that old. What is the average shelf life of fish sauce once it's open and what is the best way to store it?
