Thai cuisine employs a number of sauces and seasonings in food preparation and each plays its own role. The number of different labels and bottles can, however, be mind-boggling, so below is a brief description of the major sauces and their uses. This is not a comprehensive list.
Light soy sauce / thin soy sauce (see ew khao - ซีอิ๊วขาว)
Light soy sauce is also called white soy sauce or thin soy sauce. This is your basic soy sauce, but with a Thai twist. Thai soy sauce has a mild and soft salty flavour not present in many other Asian soy sauces, hence I don't think non-Thai varieties are appropriate for use in Thai recipes (but they work fine, don't worry). My favourite brand is Healthy Boy, which comes in both large and small bottles. If you need to replace fish sauce in a recipe, use thin soy sauce and some salt.
Mushroom light soy sauce (ซีอิ๊วขาวเห็ดหอม) can be used interchangeably with plain light soy sauce. It's a matter of preference.
Seasoning sauce (sot prung rot - ซอสปรุงรส)
Seasoning sauce is most easily recognised by its green lid. Golden Mountain brand is my favourite, but despite the difference in taste it's interchangeable with Maggi seasoning (which is commonly found as a condiment in Thailand). Often considered the secret ingredient in Thai cooking, you'll probably love this stuff so much you'll need a new bottle before long. When seasoning sauce is called for in a recipe, assume it's referring to Golden Mountain brand, which is ubiquitous across Thailand. Healthy Boy also makes a good version.
Dark/Black Soy Sauce (see ew dahm - ซีอิ๊วดำ)
Things start to get confusing with dark/black soy sauce since there are many varieties, each with its own subtleties and varying levels of sweetness. I keep two on hand, one sweet bottle and one that contains molasses and is bolder and less sweet. Dark soy sauce is thicker than white or thin soy sauce, with a viscous, syrupy consistency. It is different than Chinese dark soy sauce.
Dark/Black Soy Sauce is sometimes labelled as stir fry seasoning sauce (not to be confused with the seasoning sauce mentioned above), this is a strong and bold, salty and somewhat sweet soy sauce with a strong molasses flavour.
Dark Sweet Soy Sauce (see ew waan - ซีอิ๊วหวาน)
Dark Sweet Soy Sauce is not dissimilar to Indonesian kecap manis. This syrupy sauce is thick, dark, and sweet. This is an essential ingredient in pad see ew and is often used as a dipping sauce.
Fermented soybean paste (Tao Jeow - เต้าเจียว)
Fermented soybean paste is also known as yellow bean sauce and salted soy beans. Tao jeow will heighten the flavour of just about any food. It's available in a slightly more chunky blended form, like pictured, and as split fermented beans in brine. Use in stir fries, rat na, and stir fried morning glory.
Sukiyaki sauce (nam jim suki - น้ำจิ้มสุกี้)
Sukiyaki sauce is served alongside sukiyaki (also called steamboat or hot pot), a communal dish where a pot of simmering broth at the table is used for cooking fresh ingredients such as dumplings and vegetables. Suki sauce was developed to accompany the Thai variation of the steamboat, and is suitable for pretty much vegetable you'd have along with your hot pot. Not a traditional preparation, but I also enjoy it mixed through noodles because it takes four seconds and sometimes I want four second noodles.
Thai sweet chilli sauce (nam jim gai - น้ำจิ้มไก่)
Thai sweet chilli sauce is a versatile condiment that can be used as a dipping sauce or marinade for just about anything. Its name, nam jim gai, translates to chicken dipping sauce as it is served with grilled chicken. This sauce is excellent with grilled foods or deep fried foods like spring rolls.
Sriracha (sot see rah shah - ซอสศรีราชา)
Sriracha, which is not pronounced like see-rah-cha or see-rah-chee (it's see-rah-shah), is available in varying degrees of heat. This bright red garlicky chilli sauce also appears to be one of the most popular non ketchup table condiments in many countries outside of Thailand, but there is a gulf of difference between Thai sriracha and the style of Huy Fung and Flying Goose brands. The difference is Thai versions are a little sweeter, less garlicky, and thinner than those popularly available in North America and European supermarkets. I love both and use them liberally.

I need to seek out the rest of the healthy boy brand, I get the mushroom one all the time but I've never seen the others!
Kip says
The mushroom one is ace!
Louis says
Read the ingredients - this brand is best-selling in Thailand but has high sugar, msg … seek out a better quality sauce !
Kip says
The myth that MSG is bad for you has been scientifically debunked time and time again. It is a safe ingredient.
vegan miam says
Love all of the condiments, use them in my Asian dishes almost everyday!
Kip says
Same! I practically drink Thai soy sauce.
Caitlin says
I feel like I know way more about soy sauce after reading this! I love the educational articles, thanks! 🙂 Where do you buy all these? Is there a Thai specialty shop or will anywhere in Chinatown sell them?
Kip says
I've got a post scheduled for sometime this month with London resources for finding Thai ingredients, but in the meanwhile you will find many of them in New Loon Moon in Chinatown 🙂
Gabrielle says
Where's the Kikkoman?
wise guy says
Kikkoman isn't Thai, but Japanese. Very different taste and not interchangeable as the author says.
"Thai soy sauce has a mild and soft salty flavour not present in many other Asian soy sauces, hence I don't think non-Thai varieties are appropriate for use in Thai recipes."
Gabrielle says
It was a joke
Will says
I think you made a mistake with the Sweet soy sauce. You just wrote the same thing as black soy sauce but with a different spelling. Thai sweet soy sauce is "see ew waan"/"Siu wahn"
Kip says
So I did. Thanks for the correction!
Suzi says
I'm having trouble tracking Thai sriracha where I live, my local Asian grocer doesn't have any. A search online reveals some online Aussie Asian grocers selling a Thai green sriracha, and I have the option of having Flying Goose brand shipped from the UK.
Is there something similar I can use to Thai sriracha? Is the green likely to be very different from the red?
I love this post, very informative! I couldn't get the Black or Dark Sweet Soys locally either, but could order them online.
Kip says
Hey Suzi,
Thanks for your nice words 🙂
Can you get Indonesian kecap manis? That is a reasonable stand in for the dark sweet soy sauce. As for the sriracha, maybe you could make your own? Hot Thai Kitchen has a simple recipe, and her site and Youtube channels are great resources in general. I've never had green sriracha so I can't answer definitively, but I'd expect it to have quite a different (but good) flavour. Let me know if you try it! Flying Goose is a good hot sauce, but it is unlike Thai sriracha, so if I had to choose I'd go with making your own.
Gene says
Mushroom suace is it halal
Kip says
Hi Gene,
I don't know enough about the laws that govern what makes a food product halal or not so I'm afraid I'm not in a position to answer this question.
Peter says
Just a heads-up that many sauces, including golden mountain sauce contain isosinates made from animal by-products, which many be an issue for vegans.
Kip says
The components of disodium ribonucleotides are sometimes produced from animal sources, but they can also be made from plants (e.g tapioca starch and seaweed). Since Golden Mountain sauce is labeled vegetarian I am happy to assume the latter. The Vegetarian Resource Group posted an article about this awhile back: https://www.vrg.org/blog/2011/03/21/disodium-inosinate-and-disodium-guanylate-are-all-vegetable-flavor-enhancers/
K says
Oh no, healthy boy has msg and lots of additives, so I guess there is no authentic Thai kitchen without msg? I think my boyfriend's mum had this, but she is Chinese so not sure. But I think she might have been feeding us oyster sauce in vegan 🙁
Kip says
There is no good, peer reviewed research that indicates MSG is bad for you. Not one paper. Hence it isn't something to worry about. The oyster sauce thing is frustrating and I have faced similar difficulty in some places. Now I just specifically say no oyster sauce to be extra clear.
Shreya says
Hey! I visited to a Thai restaurant in Randwick yesterday, and they served us with a peculiar flavor sauce. Now that I’ve read your blog post, I know exactly what it was. Sweet Soy Sauce was it is . Thank you for writing this article.
Chantal says
Which one is the regular soy sauce? Salty and dark?!
Kip says
The regular one is the thin, light one.
Elisa Davidson says
Thank you for this description of the sauces. I am very allergic to fin fish and other seafoods, so I am very thankful for vegan alternatives. I have been using thin soy for years as a substitute for fish sauce, but do you have a better suggestion?
And what would be the best substitute for oyster sauce?
Kip says
