STEP 3/4
Add sliced onions and eggs. After adding onions and eggs, don't just stir it, and if you stir it just enough to mix it, the egg won't break, so you can have a clearer soup.
STEP 4/4
When the noodles are almost cooked, add the blanched bean sprouts and boil slightly.
To add raw bean sprouts, when the noodles are about 2/3 cooked, add bean sprouts, cover them, and boil them until they steam.
If you add onions and vegetables from the beginning and put them when the noodles are slightly cooked, you can feel the soft texture of onions and vegetables!
