The BEST Japchae Recipe, period.

Hi guys!

Finally! I’ve redone my Japchae, Korean Glass Noodles recipe!

The original recipe was created in 2012 so it’s been over 7 years!!
I’m still making my japchae exactly the same way because this recipe is THE BEST and THE PERFECTION!!

The only thing I’m doing differently now is just tossing the egg omelet into the noodles, instead of using it as garnish.

It’s definitely one of my signature menus and I’m so happy to redo this recipe with upgraded production for you!!
