A traditional artisan bake offering a delicate, buttery crumb and golden exterior, served fresh with clotted cream, preserves, or rich salted butter.
Mix the flour, yeast, sugar, and warm water into a soft dough and rest for 1 hour.
Season the pork with soy sauce and sesame oil, then fold in the chopped gelatin stock cubes.
Divide the dough and press into rounds, spoon in the filling, and pleat into buns.
Place the buns seam-side down in an oiled, covered frying pan and pan-fry over medium heat until the bases brown.
Pour in the water, cover, and steam for 10 minutes until the buns puff.
Uncover, cook off the liquid, and serve with black vinegar.
