About
Japchae is glass noodles that should stay springy and separate, each vegetable cooked on its own so the colours stay honest. The seasoning is soy, sugar and sesame oil — not chilli. It is served at celebrations and also from a plastic container at room temperature. Both are correct. Soak dangmyeon until flexible, then give them a short boil so they stay springy; a long boil turns them to glue. Season the noodles in their own bowl with soy, sugar and sesame oil. Cook each vegetable separately so the colours stay clean, then toss off the heat. Done is glossy, separate strands and vegetables that still taste of themselves; wet spinach will grey the whole pan.

Scaling multiplies the written quantities. Baking still prefers a scale.
Steps
Step 1
Boil dangmyeon until just flexible, 6–8 minutes. Drain, cut into shorter lengths with scissors, and toss with 1 tbsp soy and 1 tbsp sesame oil so they do not set into a brick.
10 minStep 2
Blanch spinach, squeeze, season with salt and a drop of sesame oil. Sauté carrot, onion and mushroom separately with a pinch of salt — each should stay bright.
12 minStep 3
If using beef, sear quickly with a little soy and garlic. Cook a thin omelette and slice.
6 minStep 4
Toss noodles with remaining soy, sugar, sesame oil, garlic and pepper. Fold in vegetables and beef. Taste: savoury-sweet, not salty soup. Sesame seeds.
3 minTip: If it tastes dull, it wants sesame oil, not more soy.

History & culture
A janchi (feast) table almost always has japchae. Home cooks often make it a day ahead. Beef is common, not required. Weddings, sixtieth-birthday tables and church buffets still expect a tray of it, often at room temperature. Home cooks make it a day ahead on purpose. Beef is common in Seoul celebration pans and easy to omit. It is feast food that also survives in a plastic container on a desk the next day.
The royal-court ancestor was vegetables without noodles. Dangmyeon arrived later and became the dish people now mean. Court japchae is often described as a vegetable dish without noodles; sweet-potato starch dangmyeon made the plate people now mean, largely in the twentieth century. Banquet restaurants then fixed the soy-sesame-sweet profile. We are not plating a Joseon reconstruction. The glass-noodle version is the modern celebration standard.
