Japchae is a sweet and salty Korean noodle dish. Made using sweet potato noodles called 당면 “Dangmyeon”, japchae has a delightful texture and a colourful medley of ingredients.
All accented with thin strips of marinaded beef and mushrooms,
I have never met a person who doesn’t like the taste of this dish.

It isn’t difficult to prepare, it just has a lot of mini-steps.

In a nutshell, you'll marinade the meat and prepare the japchae sauce. Then, cook all the vegetables, the omelet, and the meat separately. Finally, you’ll boil the noodles and toss everything together with the delicious japchae sauce.

OBANGSAEK

A note on keeping colours: we want to preserve the individual, bright colours of each vegetable.  

The Korean colour concept of “OBANGSAEK
오방색”
is prominent in this beautiful celebration dish, which is why you pan fry each vegetable individually. 

An easy rule: cook from lightest to darkest. It prevents your orange carrots dying the white onion.

BOILING THE SPINACH & NOODLES

Bring a large pot of lightly salted water to boil.  You are going to cook the spinach in the same water as the noodles, so prepare a bowl of ice water.

Not all noodles are made the same, so the time may vary:

Overcooked noodles:
very easy to bite through, soggy. 

Perfectly cooked:
a little bouncy, chewy, but soft.

Undercooked:
a little crunchy with a small bounce sensation.
