Japchae - Korean sweet potato noodles with stir fried vegetables & beef..

If anyone ever asked you what noodles are made of, you'd probably say, "wheat flour", right? But noodles don't have to be made of wheat flour. They can be made from rice flour along with mung bean starch and, in the case of this very popular Korean dish, sweet potato flour. As well as being called "sweet potato noodles", you'll also find these sold as "glass noodles" because when they are cooked, the noodles become translucent.

Although the sweet potato noodles are the main constituent of Japchar, the name itself - Japchae - actually translates as "mixed vegetables" - the "Jap" meaning "mixed" and the "chae" meaning "vegetables." because the original dish didn't contain noodles although today, Japchae without the noodles just isn't considered to be Japchae at all.

Japchae has along history in Korea, going back, it is said, 400 years to the 17th century when it was decreed to be a "royal dish" by the Emperor as he liked it so much. Apparently the cook who invented it was promoted to head of the Royal Treasury, so I hope he was as good managing money as he was with his cooking!

In Korean, Japchae is a very flexible food which can he served hot in winter and cold in summer. It can be served as a main dish or as a side dish. The vegetables in a pukka Japchae can be quite varied but the main principle is to include 5 colours being red, green and yellow, black and white. In my version, that means red bell pepper, baby spinach, spring onion, carrot, shiitake mushrooms, beef and onion. As we are talking "stir fry" all the ingredients (apart from the sweet potato noodles) are cut small to ensure that they cook through quickly.

The flavours for the dish are principally soy sauce, sesame oil and a little garlic which give the noodles and veg a rich, nutty and slightly sweet flavour - I think this is one of the nicest ways to eat noodles that you'll find. What's more, it only takes about 30 minutes to prepare, so what's not to like!
