This is how Korean moms make Gochujang at home every year in spring. This is a very authentic and traditional way to make Korean chili paste! If you have the ingredients and some time, this somewhat long process is totally worth it!
What is Gochujang?
Gochujang is a Fermented chili paste and NOT a sauce.
Yes, Gochujang is NOT a sauce ladies and gentlemen. The one you add on Bibimbap IS a gochujang sauce because the Gochujang paste is mixed with vinegar, sugar, water and any additional seasoning to make a sweet gochujang sauce.
An authentic fully fermented Korean Gochujang is made from fermented soybean powder (meju garu 메주가루), korean red chili powder (gochugaru 고추가루), sea salt, rice syrup (jocheong 조청), malted barley powder (yeotgireum garu 엿기름가루) and sweet rice flour. Additional ingredients like maesil cheong syrup, rice flour, barley can be added to make different variations.
Gochujang is a fermented red chili paste that Koreans love to add to sauces, marinades, stews, soups.. just about on everything. Make a sweet & sour gochujang sauce by mixing vinegar, water, sugar or syrup then use this on your bibimbap or just toss any fresh or steamed vegetables.
Most popular Korean dishes that use Gochujang is Tteokbokki and Spicy Pork or Chicken Bulgogi. I also have a Gochujang Oven Baked Chicken that’s my simplified version of the original.
WHAT DOES GOCHUJANG TASTE LIKE?
The gochujang paste itself is spicy, salty and slightly smoky and funky with just a hint of sweet flavor. Chances are, you probably have never tasted the full glorious flavor of the raw gochujang paste itself but rather sauces with gochuang in it.
The gochujang tubs you buy from the grocery store is much sweeter than my home fermented gochujang because the manufacturers add corn syrup to it. In fact, if you look at the ingredient list, sadly, corn syrup or starch syrup is usually the first ingredient which means that is the major ingredient.
GOCHUJANG VS SIRACHA
How is Gochujang and Siracha different?
Siracha and Gochujang are both spicy but Siracha is a mix of red chili, garlic, sugar, vinegar while Gochujang is a 6 month fermented chili paste. So while Siracha is fresher and tangy tasting as you can imagine Gochujang is a lot more complex and has deeper flavors full of umami + mild funky flavor.
In addition to spicy flavors, Gochujang is salty while Siracha is not. So be aware that when you add Gochujang, you are not just adding spicy flavors but also saltiness.
Is Gochujang hotter than Siracha?
Well.. that’s not very simple to answer because Gochujang comes in different spicy levels from mild to extremely very hot! Siracha is made with Siracha peppers and depending on the crop, it is said to have anywhere from 1000-1500 SHU (scoville heat units) on the Scoville scale.
Recently, CJ announced that their Haechandeul 해찬들 Gochujang will be made in 5 different levels of spiciness with the range of SHU numbers: mild 순한맛 (300-600), slightly hot 약간 매운맛 (600-900) , medium hot 보통 매운맛 (900-1500), very hot 매운맛 (1500-2000), extra hot 아주 매운맛 (2000 and above). So just from this, one can say that Siracha would be comparable to medium hot Gochujang but maybe more spicy or less spicy than some.
How Spicy is Gochujang?
Well, as you can see from above, Gochujang spicy level can range from mild to very hot with their SHU levels going from 300 all the way to 2000 and plus. But the average one is around 900-1500 SHU which is quite mild in the scale of chili peppers. In my personal opinion, much like anything, if you add a lot of it, it will be spicy while if you add just a little bit of Gochujang, it will add great complex flavor while not making it too spicy.
If you asked me 5 years ago, whether I make my own Gochujang, my response would have been something like – “No…..I don’t do that…that’s too much work.. oh, only our mothers did that.”
But here we are, in my 6th year of blogging; I have already attended two Gochujang making classes (in Korea last February) so that I could make it at home this year. During my recent stay in Korea, I got to taste some great homemade gochujang and deonjang and I realized store bought gochujang and homemade gochujang is just not the same. In addition, I have also discovered that not all gochujang sold at stores are the same.
WHICH GOCHUJANG SHOULD I BUY?
Did you know that often a not-so-good gochujang has corn syrup, starch syrup and even hydrolyzed vegetable protein as part of their ingredients??? A good quality gochujang should have minimum ingredients – only have chili pepper powder (gochukaru), fermented soy bean powder (mejukaru), sweet rice/rice/brown rice/barley/wheat flour, rice syrup, malt barley syrup or powder and salt.
And even if it has corn syrup, at least don’t buy one that has corn syrup as it’s first ingredient. I mean..imagine.. how much corn syrup that is!! Sometimes some alcohol is added to stop the fermentation process but that’s it. So please read the gochujang ingredients carefully.
In Korea, there are many great quality gochujang in the market but sadly almost none of them are sold in the US… or outside of Korea.
The Ingredients needed to make Gochujang
FINE KOREAN RED CHILI POWDER (고운 고추가루 GOEUN GOCHUKARU)
Gochugaru or Korean red chili powder is the most important ingredient for this wonderful hot pepper paste. As you probably know, each chili has a different level of spiciness but also a different flavor profile. Korean red chilis have the perfect balance of spicy and sweet flavor to really make the best gochujang so please do try to use a Korean one.
We use both COARSE and FINE gochugaru in Korean cooking. Below you can see the 2 different kinds. FYI, the left one is darker in color because they are last year’s crop. Gochugaru becomes darker in color when they are over 1 year old. The fresh crop Gochugaru has brighter and more orangish red color.
Coarse Korean red chili powder (Gulkeun Gochugaru 굵은 고추가루) is what is used the most in Korean cooking these days and over 90% of Gochugaru sold at markets is probably coarse. Traditionally coarse red chili powder was used in making all kinds of Kimchi except for water Kimchi (mul kimchi 물김치). Coarse gochugaru gives you brighter red color and has a cleaner flavor with even a bit of a zing. It is also used to make jjigae, guk and namul.
Fine Korean red chili powder (Goun Gochugaru 고운 고추가루) is definitely needed in making gochujang and then for mul kimchi. Look for bags that say “고추장용” which means it’s for making Gochujang. Also used to make refined sauces and sometimes used for making more elegant moosaengche. Fine gochugaru produces less clean almost kind of a muddy taste and thus not usually used for fresh vegetables but can be used for stews and soups.
If you want to make a hotter gochujang, try substituting a part of the chili powder with some red Cheongyang chili pepper powder.
MEJU POWDER (메주가루 FERMENTED SOYBEAN POWDER)
Meju is a block of cooked soybeans that are fermented with salt and water to make soy sauce and Korean soybean paste (Doenjang). Meju powder is the crushed and powdered form of the soybean blocks. So the meju powder is the ingredient that gives real authentic gochujang its funkiness.
FYI, Japanese miso is very similar to Deonjang and so I know there are recipes out there that use miso paste as the base for making Gochujang. Please know that miso paste is NOT used in traditional Korean Gochujang recipe. It’s just a quick way to make something similar. It will totally miss the funky complex awesomeness a properly fermented gochujang will have.
You can READ MORE about Deonjang in my Know your Doenjang post.
YEOTGIREUM GARU (엿기름가루 MALTED BARLEY POWDER)
The role of the Yeotgireum Garu is to break down the starch of the sweet rice flour (or other flours like barley or wheat if used) into simple sugars with its enzymatic activity. Once the starches are broken down the various bacteria from the meju powder and air will ferment the gochujang over 6 months.
My favorite to use is the Korean malted barley powder that’s still coarse enough for you to see the barley husks. If you need to buy a substitute for Yeotgireum Garu, then try to buy diastatic malt barley powder where the enzymes can be reactivated once hydrated.
KOREAN SEA SALT (천일염 CHEONILYEOM)
You may think salt is a salt.. no..
Did you know that different salts based on where they are sourced (land vs sea), how they are produced (boiling, drying in sun etc) the salinity per volume is different and also the flavor profile is different.
Korean sea salt have a more earthy and slightly bitter taste than other salts while having lower sodium than most. So if you used a non-Korean salt, you will need to adjust the amount based on the different amount of salt. To see how different salts can be, you can read my Best Salt for Kimchi post where I compare 12 different salts. Also, just because it’s Korean salt, doesn’t mean they are the same so be sure to use the Coarse Solar Sea Salt (Cheonilyeom).
RICE SYRUP (조청 JOCHEONG)
Korean Rice Syrup is made by first breaking down cooked rice with malted barley powder soaked in water. The resulting liquid is similar to Sikhye and then this is boiled until it is reduced to syrup consistency. Commerical gochujangs add corn syrup instead of Jocheong because that’s less expensive but traditionally this syrup is added to add sweetness.
Equipment needed for Gochujang Making
- 1 5 quart or larger Korean gochujang hangari (항아리)/onggi (옹기) = glazed clay vessel or pot that can hold liquid but is porous for it to breathe
- 2 large bowls (5 quart or bigger)
- fine sieve or medium grade (#50) cheese cloth
- 1 large pot (5 quart or larger)
- 1 fine mosquito net or fine mesh fabric to cover top of gochujang pot
- 1 string to tie mesh fabric
- coals, sesame seeds, metal bowl (optional)
Traditionally, Koreans make Gochujang only at certain times of the year!
Gochujang is typically made in the colder winter months between the end of November to February in Korea. It is because the 4~6 month fermentation needs to occur in FULL SUN but BEFORE the very hot and rainy summer starts in Korea.
For California, I thought February would be a great time since by then hopefully rain is getting lighter and there are more sunny days. So when I was getting ready to move back to the US in 2014, I bought and shipped Korean gochukaru (고추가루 red chili powder), mejukaru (메주가루 fermented soybean powder) and cheonilyeom (천일염 solar sea salt) via sea with our moving stuff so I could make it in CA.
And most importantly, I also purchased a Korean hangari/onggi vessel where I could ferment the gochujang in. This particular vessel was made by one of the few remaining Korean artisans who is deemed by the government to be part of Korean’s national heritage.
GLUTEN-FREE GOCHUJANG WITHOUT MALT BARLEY POWDER
If you need to be gluten-free and don’t want to use the malt barley (Yeotgireum Garu) or if you can’t buy malt barley powder, you may want to use my Easy Homemade Gochujang Recipe which doesn’t use malt barley but just rice syrup (Jocheong 조청).

Step-by-Step Instructions on How to make Gochujang at home
- 1-2 DAYS BEFORE: Sterilize your ghochujang hangari or onggi (Korean glazed clay vessels aka earthenware for fermentation) by pouring hot boiling water inside and out and drying them. OR you can use coals that have turned into white embers by putting them in a metal bowl and turning over the hangari on top so that the hangari gets filled with HOT smoke which will also sterilize the pot. I used both methods just to be sure. Here is a picture of how it was done:
The hangari will smell very smoky at first, but it will go away as you air it for a day or two. It is also the intention to have a little bit of sesame seed smoky flavor. If you don’t want this, just use hot water.
Malt barley (yeotkireum) in cheesecloth
Malt Barley liquid strained using cheesecloth
It made me happy just looking at them, smelling the beautiful and familiar smells – the spicy gochukaru tickling my nose and then the very endearingly stinky deonjang smell from the mejukaru taking me back to my childhood..to the days when moms made everything at home.
And I hope to share with you how my gochujang turns out under the California sun in the next 6 months.
The salt crystals are like little diamonds~~ love love love..♥♥♥
Well, I know this is probably not something you can make easily and you need various special ingredients and vessels but I thought I would share it with you so that at least you get to experience and know what is involved in making the amazing gochujang the traditional and authentic way.
- You can also buy Korean Traditional Earthenware for fermentation on Amazon.com. The size is not very big so you may need more than one but it should work. I have selected a few below.
- If you REALLY want to buy the Korean Hangari/Onggi in the US, try visiting a larger Korean grocery market.
- A HUGE THANK YOU to my friend Judith for asking me to post a Gochujang recipe and then also coming to my house to help me make this wonderful paste.

I so want to make this some day, but despair in mid-Wales buying all the ingredients. Hmmmmm. This is an amazing tutorial, btw.
David Kim says
Thanks for sharing this recipe! You got me really curious about the flavor of that gochujang of yours. I feel very inclined to try making it myself, but first I’ll have to find those ingredients here in Brazil. I might have to make some substitutions. Hopefully, it will turn out alright.
JinJoo says
I am currently working on a simpler recipe but you will still need meju powder. Are you able to buy that? Thank you so much for your comment and good luck!
David Kim says
There are dozens of Korean markets in São Paulo, where most Koreans here live. I’m pretty sure they’ll have it. I’ll ask my mom, who lives there and probably knows, since she recently told me she’d made gochujang for the first time. I live in the mountains, in the country side, and I’ll be favored by our climate, hot and rainy summers, and (not too) cold and dry winters. I’ll have plenty of time to get the ingredients until our winter starts.
JinJoo says
Good to know! Yes, in that case you should be able to get meju powder and other ingredients. The good thing about them is that they dont’ go bad quickly so you can have them for months before making them. If the weather is hot/humid, I do suggest you store the powders in the fridge until you are ready to make them. Good luck!
Jinju says
My name is Jinju, too! 🙂
I’m envious of your glass onngi lid! I just started my gochujang two days ago. While it’s sitting and fermenting, do you need to mix it at all? Or do you just leave it undisturbed for the 6 months?
JinJoo says
Oh Hi JinJu! Wonderful name!! haha. Oh, I know, I wish they sold the lids here.. I mean my local Korean store does but not sure where you live. So https://kimchimari.com/gochujang-is-fully-fermented-after-2-months/ is the article that talks about after making your gochujang. You should mix it when you see that the top is cracking and looking too dry. Depending on your weather and how wet/dry you gochujang mix was, you may not need to ferment it for full 6 months. Read my article for more info. Thanks for asking! Good luck!
Charles Ufford says
Thank you for this recipe! I’m not Korean, just like to cook and experiment. Saw kimchi made for food truck food so tried his recipe.
Have two ideas: if you have a warm indoor room where you don’t mind smell, you can ferment inside. To prevent mold growing, use one of those handy hanging spotlights used for workshop, growing plants or warming baby chicks. Use infrared or UV bulb and that will kill any fungi. If room not quite warm enough, use heat pad.
Other idea is at king arthur flour baking website they sell bags of barley malt powder, used in bath when making bagels so they are chewy and brown outside. Someone could investigate to see if this was appropriate substitute.
I ended up here because looking for kimchi fried rice recipe, they call for pepper paste, and me looking to see if I could make it. I’d probably make smaller recipe.
Thanks for your hard work!
JinJoo says
Those are all great ideas! It doesn’t have to be too warm, just not freezing. But using an infrared lamp sounds good too. I will definitely look into the barley malt powder from king arthur flour. Thanks for the info and neat ideas!!
Brenda Adams Bell says
I’m new to gochujang and I doubt I’ll be trying to make my own any time soon. Here in the U.S., I was able to order the premium one made by Chung-Jung-One. No corn syrup or preservatives. I’d really be interested in knowing how that one compares to the ones available in Korea.
JinJoo says
Hi! So sorry for the late response as I have been traveling. So Chung Jung One is one of the brands I recommend because they have no corn syrup or preservatives. Koreans use Chung Jung One gochujang all the time. It does NOT have the live cultures and deep, complex flavors that authentic, traditional hand crafted gochujang’s have but it is totally fine in terms of flavor. Probably a little sweeter and simpler in taste but many young Koreans are actually very used to this taste. Thanks for asking and Happy New Year!!
