In a bowl, combine the yeast, white sugar, flour, and salt. Pour the warm water, milk, and softened butter into a jug and stir until the butter melts. Gradually mix this liquid into the dry ingredients with your spoon before kneading by hand or running a dough hook in a mixer for about 10 minutes. Put the dough in an oiled bowl, cover it up, and wait 1.5 to 2 hours until it’s doubled in size.

As the dough rises, toss the chicken chunks into a bowl with the buttermilk, white pepper, garlic salt, and regular salt. Mix all those seasonings through, cover the bowl, and pop it into the fridge to chill for a minimum of an hour.

Once your dough has risen nicely, roll and knead it again. Split the dough into twenty equal chunks. Shape them into ovals (roughly 6cm by 9cm) on parchment paper. Lightly coat one side with olive oil, fold using a chopstick for space, and remove the chopstick. Leave them on their parchment, covered, to rise for another hour.

Warm your frying oil in a heavy pan or deep fryer. Set your oven to keep at a low heat (to hold fried chicken warm after cooking). Take a roomy bowl, blend all your crispy coating ingredients thoroughly, and set it aside.

Take the marinated chicken out of your fridge. Let the excess buttermilk drip off every piece, then roll the chunks in the crisp-flour mixture. Fry a handful at a time (about 10-12 pieces) for 3–5 minutes, so crispy outside, cooked-through inside. Put each batch in the warm oven as you finish the others.

Fill a steamer pan with boiling water. Place buns, still on their parchment sheets, into the steamer in small groups. Let them steam for around 10 minutes, then set them aside on a plate to stay warm.

Take a saucepan, toss in sesame oil, vegetable oil, gochujang, honey, soy sauce, minced garlic and ginger, plus the brown sugar. Let this heat up until it boils and then turn it down to bubble for 5 minutes until it thickens.

Coat the fried chicken in your sticky, hot sauce. Open the buns and stuff them with the saucy chicken. Sprinkle over the sliced onion, diced cucumber, coriander leaves, and sesame seeds just before serving.
