What is japchae?

Japchae is a stir-fry of chewy, translucent glass noodles with colourful vegetables, mushrooms and usually beef, all coated in a sweet soy and sesame seasoning. It's a fixture at Korean celebrations, holidays and buffets, and a common side dish (banchan). The name means "mixed vegetables": the original royal court dish in the 17th century had no noodles, which were added in the 20th century.

What's in it

• Dangmyeon: glass noodles made from sweet potato starch, boiled and then tossed in the seasoning
• Vegetables: spinach, carrot, onion, spring onion and capsicum (bell pepper), each cooked separately
• Mushrooms: shiitake or wood ear
• Meat: thin strips of beef, sometimes pork
• Seasoning: soy sauce, sugar, garlic, sesame oil and toasted sesame seeds
• Garnish: thin strips of fried egg yolk and white (jidan)

It's usually served at room temperature. Japchae-bap puts it on rice. Japchae noodles also fill gimmari (seaweed rolls, battered and fried) and some mandu (dumplings), both of which add wheat. At Korean-Chinese restaurants, gochu-japchae is a different dish: shredded pork and peppers, served with steamed buns.

Allergens and diets

Soy and sesame are in the standard seasoning, so assume both.

Gluten catches people out. Sweet potato noodles contain no wheat, which leads to japchae being called gluten-free online. The soy sauce in the dressing is usually brewed with wheat, and some commercial dangmyeon includes other starches, so check the packet or ask. A kitchen that can use wheat-free tamari and confirm the noodles removes the main sources, but ask about shared pans too.

The egg garnish is common and easy to leave off. Seafood japchae adds prawns (crustaceans) and squid (molluscs).

Leaving out the meat and egg gives a vegetarian dish. Many restaurants make a single batch with beef, though, so ask before ordering.
