Xiao Long Bao - Little Soup Dumplings

After throwing out the question "Which would you prefer?" in that painfully short post I made last month, I was pleasantly surprised that the majority of commenters loved the dumplings. I grew up eating xiao long bao for breakfast almost every morning when I lived in Shanghai. I think it's one of those things you absolutely must eat in your lifetime; you'd be hard-pressed to find a more perfect morsel of food. Of course, I may be biased since they are my favorite food item but if you've seen the No Reservations: Shanghai episode, I'm sure Anthony Bourdain would agree with me (even though he hates food bloggers or something like that). Hopefully no one falls asleep reading this thesis-length post--I swear I tried to edit out as much as I could. Both xlb and croissants, which will come a little later, were in the top 5 of that huge long list of things I wanted to make this summer. I was able to cook about 1/3 of the list even though I only blogged about a handful of them. As for the rest of the items, the time frame is extended... indefinitely? Gotta love personal deadlines.

The xiao long bao, also called soup dumpling, is a bite-sized dumpling in a thin flour wrapper with a pork, sometimes crab, filling and a rich broth. The soup is what sets the xiao long bao, its pan-fried cousin the sheng jian bao, and the larger relative the tang bao, apart from all other dumplings and buns. The trick to getting the soup inside the dumpling is make a gelatin rich soup that solidifies at room temperature (think meat soup Jello) then mash it up into small chunks and mix it with a ground pork filling. As the buns steam, the pieces of gelatin soup in the filling melts back into a liquid that's now magically encased in the delicate wrapper. Pretty cool huh? A well made xiao long bao will have nearly two dozen pleats in the thin, almost translucent wrapper, a tender meaty filling, and is bursting with savory soup.

Xiao long bao originated in Shanghai over a hundred years ago and have now become an iconic symbol of Shanghainese cuisine. They were created by the Nanxiang Steamed Bun Restaurant, which still sells these dumplings to this day. In Shanghai, you don’t have to travel far to find this morning staple but here in North America, there are only 3 major metropolitan areas that I know of serving this niche food item. Unfortunately, here in Seattle, you won’t be able to find any that are worthwhile. Instead, you'll have to make the drive up to the Vancouver/Richmond BC area, which has half a dozen or so restaurants serving decent xiao long bao (my favorite location being Shanghai River in Richmond). For elsewhere in the US, I've heard good things about the xiao long bao you can find in Southern California and New York City. Outside of Vancouver, SoCal, and NYC, I’m afraid you might be out of luck but if anyone finds a good city in the States do let us know! You may be tempted to buy the frozen xiao long bao sold at Asian grocery stores but usually they’re utterly disappointing-the skin is too thick, the soup leaks, and the filling is tough and studded with overwhelming chunks of ginger. But when a craving gets really, really, really bad, I'm not gonna say no.

When faced with a fresh basket of soup dumplings, don’t stick the whole thing in your mouth and chomp down. Hot juices will spurt out, dribble on your shirt, and worst of all, scald the inside of your mouth. Instead, after dipping the dumpling in a little black vinegar, place it on your spoon and gently nibble the wrapper and slowly slurp up the soup so you don't burn your tongue. Then dip the dumpling again in the black vinegar if you like a more vinegary kick before eating it. Some places will give you some ginger slivers to add to your black vinegar.

If you really want to try making this at home, I have to warn you that it’s long and time consuming. It was the most tedious recipe I have ever attempted but I'm weird and I like spending my weekend cooking something that takes 2 days to prepare. Even though the majority of my dumplings look misshapen and half of them leaked, the flavor was spot on! I did a pretty good job for a first attempt but I won't be making these again for years... So next time we'll just drive up to Vancouver for our fix.

If you're still set on making these at home, I implore you, please don't take short cuts. Don't make the stock with that can of Swanson's sitting in the pantry from 2001 *blech*. What makes these little gems special is the flavorful soup inside so spend the time to make a good soup base. It's worth it! While you could take some homemade chicken stock set it with gelatin, it will lack the velvety, almost creamy richness of a traditional slow simmered stock made collagen-rich pork feet or pork skin. For my stock, I used a combination of chicken wings, chicken backbone, and some pig feet along with aromatics like ginger, green onion, and star anise. You can use pork skin too but the meat in the pig feet will adds to the flavor. Make the wrappers fresh too because if you spend all that time making the soup and filling, it's a shame to use storebought wrappers.

Xiao long bao – Shanghai Soup Dumplings

Aspic/Gelantized Stock
1 pound chicken wings
2 chicken backbones (carcasses from roast chicken will work too)
1 pork trotter (foot) or a large piece of pork skin
3 1/4 inch thick slices of ginger
4 green onions
1 star anise
8 cups of water
Salt

Wrappers
3 C all purpose flour
1/3 C hot water
2/3 C cold water
Pinch of salt

Filling
1 pound ground pork
1 Tbsp soy sauce
1 Tbsp rice wine
1 tsp sesame oil
1/2 tsp grated ginger
1/2 tsp sugar
2 C gelatin stock, chopped/mashed into small pieces

Serve with
Black vinegar
Fresh ginger slivers

Make the aspic
When working with pork feet make sure to wash it well, then boil it twice in a change of water to get the smell, bacteria, and scum out. If you're using raw chicken wings and backbones, it's best to boil those once too to get any scum out. Add the pork feet to a pot (large saucepan, stock pot, Dutch oven whatever works) and cover them with water and bring it to a boil. Boil for a minute, drain, and rinse off any scum on the feet in cold water. Wash out the pot as well or use a new pot because there will be scum on the side. Return the pork feet, and the raw chicken wings and backbones to the pot and fill with cold water and bring back to a boil again and boil for a minute. Drain and rinse off any scum and wash the pot again

Add 2 teaspoons of oil to your pot over medium heat. Smash the ginger slices and green onion with the side of a knife and add to the oil and until they are fragrant, then add boiled and rinsed off chicken wings and pork feet, 1 star anise, and 8 cups of cold water. Bring to a boil then simmer gently uncovered, skim any scum on the surface, for 6+ hours. Never let the soup boil again because it will cloud. The stock is ready when it can solidify at room temperature. Test the stocks gelling ability by spooning some of it into a small bowl and allow it to cool down to room temperature. If it solidifies then the stock is ready. Strain soup and season it with some salt. Set aside 2 cups for the dumpling filling. Save any excess for adding to sauces or soups. Let the soup cool to room temp then transfer it to the fridge. The soup can keep for up to 3 days in the fridge. You can scrape off any fat that solidifies on top or mix it into the filling, up to you.

Make the dough
In a large bowl, add 2 1/2 cups of flour. First add the 1/3 cup of very hot water and stir that into the flour. Then add the 2/3 cup of cold water and stir it into the dough. Bring the dough together and knead while incorporating additional flour if you need to, until the dough is not sticky. Don’t overknead or it will be too tough and gluteny to work with. Cover the dough with plastic wrap and let it rest for an hour while you prepare the filling.

Prepare the filling
Mix the ground pork with all of the seasoning ingredients. Roughly chop the aspic then use a pastry blender or two forks to mash it into smaller pieces. Mix this into the ground pork mixture. Keep it in the fridge until the dough has finished resting.

Wrapping the dumplings
Divide the dough into 3 portions. Work with one portion and keep the other two covered. Roll the dough into a long snake. Then cut a small cylindrical piece off of the snake. Flatten with your palm and roll the dough out into a 2 1/2 inch diameter wrapper. The best rolling device for making Chinese wrappers is a small wooden dowel thats about 6 inches long and 3/4 inch in diameter.

The first 4 pictures in the eating Chinese xiao long bao tutorial shows the process of making the dough and wrappers. You want the wrappers to be a bit thicker than wonton wrappers. If the wrappers are too thin, the soup will dissolve it and leak out.

Place about 2 teaspoons of filling in the center of the wrapper. Hold the outer edge of the wrapper with the thumb and index finger of your dominant hand. Using the other thumb and index finger, hold the edge of the wrapper and bring it to your dominant hand to pleat. Pleat around the circumference of the entire wrapper, turning the dumpling as you go, and seal the tip to close. The third and fourth pictures in the third row of the eating Chinese xiao long bao tutorial gives a somewhat helpful guide. The hardest part for me was getting my thumb out of the inside of the dumpling and sealing the tip.

Steam and serve
Bring some water to a boil in a wok or large pot with a steamer insert. Line a bamboo or metal steaming basket with cabbage leaves or damp cheesecloth. Place the dumplings in the basket and steam on high for 5 – 7 minutes. (5 minutes was enough for my dumplings but make sure the filling is cooked all the way before eating)

Serve hot with ginger slivers and black vinegar.
