I always have this starch extracted from potatoes on hand because it’s essential for achieving the supreme crunchiness for fried dishes like Korean fried chicken. I also use it as a thickener. I’ve never found any potato starch that worked better than Korean brands for this purpose. Seal the package well and store in a cool place.

    Hi maangchi!

    For the potato starch powder, can we use regular potato starch from the different store and not from the Korean store?? It’s for the yangnyeom-tongdak dish.

  6. Hello mangchii!
    I would really like to try this recipe but i would like to know if i can substitute the potato starch for corn starch or tapioca starch. THANKS :) :)

  7. Hi Maangchi,
    May I ask you, the potato starch that sell in korean store, is it the same with “katakuri-ko starch” which is potato starch that use in japanese dessert recipe, for dusting (such as dusting the rice cake daifuku, the sweet rice cake that have red bean inside, and using katakuriko starch/potato starch for dusting out side)?
    When we do sweet rice ball with red bean inside (your recipe), Can we use korean potato starch for dusting rice cake instead of roast soy bean powder?

    I already got most of the ingredients today – but I was wondering if I could substitute potato starch w/ either tapioca starch or corn starch?

    I always get this at a Korean store, but I think you can get it at any store.

    Did you get it at Korean grocery store? Then it must be potato starch powder. It’s translation mistake. I bought the same thing a while ago! It’s definitely potato starch powder.

  13. Hi Maangchi,

    I accidently bought “Potato Powder” instead of starch (apparently I need to work on my Korean..), what can use it for?

    You can use potato starch for many dishes. It never goes bad, just keep it in an air sealed container to use next time. When you make stew, if you like to make your stew sticky, you can use it. Check out my black bean noodles recipe. I am showing how to use it.
