Soak the dried shrimp in warm water until soften, about 15 minutes then finely chop them
Put the cooking oil in a saucepan and saute the garlic for about 10 seconds. Add the dried shrimp and saute for another minute. Add chicken broth and bring to a simmer. Add seasonings. You can prepare ahead up to this point
When ready to serve:
Bring a small pot of water to a boil and then blanch the egg noodles briefly, about 30 seconds or so
Bring the broth back to a simmer, add the choy sum and noodles and cook until the veggies are soft and noodles are heated through and the soup is slightly thickened
Since I use a cooked spaghetti noodles instead of egg noodles, the soup isn't as "thick" compared to using egg noodles. I thicken it with cornstarch solution. Combine cornstarch with water and then stir into the soup and cook until it thickens slightly
Portion the noodles along with its soup into individual serving bowl. Serve with sprinkle of fried shallots and hard or soft-boiled eggs if you choose to. Serve immediately
Notes
You can also use dried pasta like spaghetti or fettucine if you can't get egg noodles. If using dried pasta, you will need about 200-250 grams
