The food sold by streetside vendors usually is connected with junk food, fast food. Most of them are, but this one isn't.
When I was a kid my mom ran a tiny store selling some popular street food like soy pudding and chicken soup. Next to us there was a couple selling fish ball and lettuce soup.
Everyday after school I got to work at the store. One of the favorite parts of my job (it's soooo important to create fun from work :) :) was, going to the next store and looking into their soup's pot during the closing hours. All the soup was gone and left with a mountain of fish heads, fins and tails etc... why kid so amazed with such battlefield-like scene?... Those bones were never thrown out, the couple everytime just added in more new bits before making another batch of soup base. So every essence from old bones and a fresh taste from new bits all went into one soup pot!
Then the couple proceeded to washing and chopping the lettuce, mincing fish meat and checking every bottle of sesame oil. They prepared their soup exactly what every mama did at home except in a larger scale, so which never was junky nor fast.
Back then I could resist the calling from ice-cream truck and saved my money for their fish soup! With that light broth, tender fish balls, and peppery and sesame aroma, I almost quited from my mom to work for the couple :D
The street vendors don't really shape the fish paste into ball ... think of selling a hundred bowls a days it is just impossible to hand-make a thousand of fish balls. The vendors scrape a bit of fish paste into boiling soup with a wet spoon, so their fish balls are always irregular in shape. But just to cook to a few people, it really doesn't trouble me when I shaped the fish balls by hand.
The authentic version adds with a lot of white pepper and sesame oil, but now I'd like to try another version that skips the two, but put into arugula to maintain a peppery taste in soup.
Recipe of White Fish Ball, Lettuce and Arugula Soup (for 2 persons)
To make the soup base, you will need:
- fish bits (tails, fins, bones, heads, etc) of at least 3 fish
- shrimp's shells and heads, a big handful
- 2 cloves of garlic, diced
- 1 small carrot
- 1 leek, or spring onion, white parts only
- oil, salt and pepper
- water
Pre-heat some oil in a pot, saute the garlic and leek/spring onion over very low heat for a minute, then add carrot and water. After the water boils, drop the fish's and shrimp's bits, continue to boil the soup over medium-low heat (with little bubbling is good) for 1 - 2 hours. Salt and pepper to taste.
Best to leave the soup base overnight.
To make the white fish balls, you will need:
- meat from one whole fish (the meat preferably not firm and flaky, I used dory)
- 3 - 4 shrimps, shelled
- spring onion, green parts only (or parsley if you prefer), finely diced
- 1 tablespoon corn starch
- 1 tablespoon of oil
- salt and pepper to taste
Mince the fish meat and shrimp until they turn into paste, combine with oil, corn starch, salt and pepper. Shape into small balls, about the size of hazelnut
To finish up the dish:
In a serving bowl, place some chopped lettuce in the bottom.
Bring the soup base to boil, drop the fish balls in and cook until they just cooked, probably only take you a minute (overcook will make the fish tough). Spoon the soup and fish balls into the serving bowl. Drop a handful of arugula on top. Serve immediately.
