The real magic trick of a Xiao Long Bao is that soup-filled center, a gelatinous secret that melts into liquid gold. You can’t just pour broth inside a dumpling; you need to make a gelatin-rich aspic first. Simmer pork skin and chicken feet with ginger and scallion for a few hours—it sounds fussy, but your slow cooker is your best friend here.
Strain the liquid, chill it overnight, and you’ll wake up to a firm, jiggly jelly that you can chop into cubes. That firm jelly is your liquid gold waiting to happen. Pro tip: freeze the jelly cubes for ten minutes before wrapping—they’ll hold their shape and give you a much easier folding window.
