Soup dumplings are a food that are as impressive from a technical standpoint as they are from a taste one. Not only are they delicious, they also raise certain architectural questions: Particularly, just how did that soup get in there?
Does the dumpling form a bowl, which is then covered and cooked? Is the soup poured in after the fact into a hot dumpling? Magic? Nope, it's meat jelly.
In this video from Lucky Peach, you can see the whole process unfold, particularly the curious process that fills each dumpling with hot soup. As you can see above, a solidified bit of pork soup is dropped into the middle of an uncooked dumpling before it's closed. When the dumpling is steamed later on, that bit of pork jello melts down, filling the dumpling with hot soup.
