Korean hot pepper flakes are an essential ingredient in Korean cooking, used in many side dishes, soups, and stews, and in the most important Korean side dish of all, kimchi. They come in mild (deol-maewoon gochu-garu 덜매운 고춧가루) and hot (maewoon gochu-garu 매운 고춧가루) versions. For dishes like kimchi, I use the milder flakes so that I can add a lot for color without making the dish too spicy. My favorite is Bitggalchan brand from Yeongyang, Korea (it’s often sold out).

My readers often ask me if they can use chili powder or other crushed chili flakes as a substitute, but they won’t work with Korean dishes because they have a different flavor and are too spicy. Sometimes Korean hot pepper flakes may be mislabeled on the package as “powder,” but all packages will be at least partially transparent, so look inside and make sure they are coarse flakes. Beautiful bright red is best; avoid any that are purplish or brownish. When the flakes go bad, they become a yellowish-red and the flavor goes off.

After opening, store the pepper flakes in a zipper-lock plastic bag in the freezer for up to 6 months, and keep a small amount in a jar in the refrigerator for everyday use.

Buying hot pepper flakes can be difficult if you don’t read Korean because many Korean manufacturers will mislabel the product in English so it’s hard to know if you’re getting hot pepper flakes at all.

Take a look at the product in the package if at all possible. Hot pepper flakes are always coarse and chunky.

This one is tricky because in English it says “Red Pepper Powder,”and underneath that it says “Piment” which is French for “red pepper” or “spice,” and then there’s another label that reads “Coarse.” But this is really a bag of hot pepper flakes. You can tell by looking at the big flakes through the transparent part of package.

Red pepper powder is actually something very different. They’re a lot finer and mainly used for making gochujang, so you need to be careful of what you’re buying.

    The hot pepper flakes I got figured out. My problem is what type of fresh hot peppers do I buy? I’ve been getting these ones called “Finger Peppers” because they look similar to the ones used in Korean cooking. They are green at the store and if you wait a few days they turn red. But they are crazy spicy and I cannot handle more than the tiniest piece! Is this the right pepper and I’m just (as the Japanese would say) baka gaijin?

    Mama Maangchi, i forgot to buy a pack of hot pepper flakes recently.. I traveled 2 hours just to get to the Korean store in the city (i’m living in a town province). Since, i’m already at home (lol!), should i just use/buy a hot pepper powder instead? Well, i’m not really sure as sure if there’s really a hot pepper powder in the market hahaha! Maybe the hot pepper flakes and the hot pepper powder are just the same… I HOPE~! n_n sorry for my horrible english grammar.. XDD

  3. Hi Maangchi,

    I have the one on the last picture… It suppose to be red,right? The one I got was blackish.. Is it still good to use in kimchi? Thanks and more power.

    I’ve tried the ones labeled “hot” but find them pretty mild as well. The best I had was a package my grandmother sent us from Korea one year, but I think it was homemade (sent over in ziplocks). Super hot and super tasty. Grandmom’s over a hundred now, so I don’t think she makes it anymore.

    I have used the brand of hot pepper flakes in the bottom photo, as well as another brand that is not pictured. I use a TON of flakes in my kimchi (the maximum that Maangchi lists in her recipe, plus 1/2 cup!), yet do not find it very hot. I typically add Sriracha sauce before I eat it.

    While I do love spicy food, I do not think I have abnormal tolerance for spiciness. Do you think my hot pepper flakes are expired? Do they lose their heat over time? I have heard that toasting spices in a pan before using them can restore some flavor. Would this help?

    • Maangchi New York City joined 8/08 & has 12,045 comments

      lol, you seem to love suicidal level of spiciness! Actually there are 2 types of hot pepper flakes sold at a store: mild hot pepper flakes and spicy hot pepper flakes. Mild version? You may be wondering, but ask the sales person to help you.
      You can say, I want to get very very spicy hot pepper flakes!

      In this page, the first photo of hot pepper flakes says, 덜매운 고추가루 which means less spicy hot pepper flakes.

        Thank you! I have copied down the characters and their meanings on an index card, and I’m going to the Asian grocery tomorrow to see if I can find hot ones.

        If I can’t, I will try asking the owners, who are very nice, but do not speak much English. Sometimes I think I overwhelm them when I ask questions, so I try to figure things out on my own. Thanks so much for your help!

    Hi Maangchi!

    Do you know from which hot pepper it is?
    I used the ones I have home… and even if it wasn’t much, my kimchi was really spicy!! I can’t really eat it since it’s too hot! D:

    I asked my mother and it turns to be a pepper from Thailand, known to be very very very hot(named Khi Nu).

    I have medium hot pepper powder too (no flakes) and I was wondering, if I can mix them… What do you think?

  11. LisaL USA joined 9/09 & has 19 comments

    Ah I should’ve looked at this before I asked my question on the boards heh.
    I know what the fine powder looks like, but never noticed the larger chunks before.
    My husband bought me some of the coarse powder and sure enough, it’s the correct stuff :)
    Now I’ll know what to look for next time I need more :D

  12. i like your recipe very much. i will try to make it. God bless you.. Baxia

  13. Hi!! Just made some turnip kimchi and it came out tasty (but of course, not like my momma’s!). Unfortunately, there was an “off” taste, though. Could my pepper flakes have gone bad? I can’t read Korean, so I couldn’t find an expiration date on the bag. The bag was 2 years old, though. :o) Love Love Love your website and I refer all my friends to it via Twitter and Facebook!

  14. hi!!:D i finish the kimchi && it looking great but it not that spicy at all, so i was wondering if i can wait till it fermenting and then add more hot pepper powder to it (the one that u use) cuz i try this different one and it not that good

  15. Hello Maangchi. im havnig alot of trouble finding the hot red pepper flakes.. so was wandering if you know what the “pepper” is called what fruit or vegetable the pepper flakes are made from ? if i knew that i could make some my self instead of using endless time on looking for the pepper flakes in shops and online stores because iv been allmost all over the place now and still cant find it >_<

    thanks : )

  16. Maangchi: I hope I’m not asking a question already answered. Red pepper powder and hot pepper powder. Is it the same or different? Looks the same to me, but I’m not sure if there is a difference.

  17. hi~
    I wonder where can i find the hot pepper flakes?
    Do they only sell them in korean market?

  18. Hi Maangchi,

    I was wondering if you have any suggestions on storing hot pepper flakes? Is it better to store it in the pantry or in the fridge? I’m not Korean so, I don’t use it all the time. Any suggestions would be greatly appreciated. Thanks!

  19. Hello Maangchi!

    Thank you for teaching us recipes!
    I tried to make kimchi, but it wen´t wrong, coz I used pepper power instead of flackes T.T
    Ohh.. and it´s not easy to wash the cabbage.. if we just pour water, it won´t come clean =S

    Maangchi, have you watched korean programm called “Family Outing?” they make dinner and breakfast, and few recipes look good as yours
    They made potato pancake, which I tried to made, and it turn delicious!
    Maybe you can find some inspiration watching the program!!
    Thank you once again!

  20. Hi Maangchi,
    I’m making “Cold Spicy Celery” from the Epicurious.com website. One ingredient (the one I don’t have!) is “1/2 teaspoon Korean chile flakes.” Is the taste of Korean chile flakes different from that of the red pepper flakes you buy in an American supermarket? I’d hate to have to buy (and search for) the item as written and then have so much left over! I live in NYC so it’s not hard to find, if absolutely necessary. Please advise!

  21. hello Maangchi, I love your website. Uhm… I’m not sure if I can find the hot pepper flakes, so I wanted to ask if it is possible to make it myself

  22. i went out and bought crused red pepper at the korean grocery market today..is that the same thing as red pepper flakes?

  23. You are owesome!!!!

  24. Hi!
    I tried making “oisobagi” today, but instead i used chilli powder
    and it turned out REALLY spicy.
    is chilli powder really different than the korean hot pepper flakes?
    or did I use too much powder?

    • Maangchi New York City joined 8/08 & has 12,045 comments

      I’ve never used chili powder, so I can’t give you right answer.
      However, I’ve recently heard that chili powder is different from hot pepper flakes. Yeah, if you can’t get hot pepper flakes, use less amount of chili powder next time you make your kimchi then.

      • Yes that’s right. I put less than half a cup of chili powder in my kim chi and it was alredy quite spicy! While it takes like 4 cups of korean hot pepper flakes. I thought it would be my personal taste (koreans like spicy!), but I think it’s because of the ingredient.

        My kimchi seems to taste pretty good so I think that it’s not really a problem. But maybe I will get in the neighbourhood of the Korean store in Rotterdam next week so I can buy the real thing.

  25. hi maangchi,
    is there a substitution for hot pepper powder? i read somwhere that cayenne pepper can be used. would that work, or would it just ruin the dish?

  26. Jasmine Tan& has 2 comments

    Hi Maangchi – should I use red pepper with salt or without? I saw that some came mixed with salt.

  27. Hello maangchi, i love your site and i try the egg side dishes. now im planning to cook Ginseng chicken soup. thank you… and God Bless.

    • Maangchi New York City joined 8/08 & has 12,045 comments

      Thank you for your update! I hope you read this before making your ginseng chicken soup. If you are not accustomed to ginseng taste, I suggest using one root for each serving. 2 may be too strong for you.

    mingrae0527,
    Even if you use it lesser, the flavor of hot pepper flakes will not be changed.

  29. mingrae0527& has 1 comment

    if i happen to have bought the spicy ones what can i do to make the dish (let’s say cucumber kimchi) less spicy? if i use amount lesser would the flavor change? thank you

    June,
    Why not! Try it out! : )
    Happy New Year!

  31. HI Maangchi

    Many thanks for your recipe. I am officially addicted to kimchi. I am thinking of making it but I cannot find hot pepper powder. I have have crushed chilli flakes. Can I use them instead?

  32. Maangchi New York City joined 8/08 & has 12,045 comments

    Indri,
    I think it’ll be ok unless the red chili is too spicy.

  33. Hi Maangchi,

    Instead of hot pepper flakes, can I substitute it with dried red chili? I stayed in Indonesia, we have two types of red chili, one is smaller and thinner, another is longer ones, but not as big as in western countries.

  34. Maangchi New York City joined 8/08 & has 12,045 comments

    Sarah,
    You can use either hot pepper flakes or hot pepper powder. I use hot pepper flakes.

    • Hi, haha I’m like stalking you today, all over your website ><.

      What’s the difference between the flakes and powder? Besides the texture, I mean. I asked my mom and she said that if you use the powder in soups, it makes it more grainy tasting or something? But I think it makes the soup more opaque and stronger tasting than if you use flakes…? (Hopefully this question made sense).

  35. Hi! I want to make your soon doo boo recipe. When I went to the Korean grocery store, I saw two types – the chilli flakes and the more finely ground chilli powder.

    I forgot which one you use, so I told them I want to make soon doo boo. They said I should buy the chilli powder. Now I see that you’re using the flakes and not the powder. Are they the same? Or should I go back and buy the flakes?

    Thank you!!
