1 To make the bao buns, mix the yeast with lukewarm water and leave to stand for 5 minutes. Meanwhile, combine all the other dry ingredients into a mixing bowl. Using a stand mixer on a slow setting, gently pour the yeast water into the mixer and knead for 3 minutes. Slowly add oil and knead for another 2 minutes. Transfer to an oiled bowl and allow to prove for 1-2 hours or until doubled in size.
2 Once the dough has proved, roll into individual balls and transfer onto a square of baking parchment individually. Allow the balls to prove again for another 20 minutes. Steam bao buns for 10-12 minutes until light and fluffy.
3 To finish the sandwich, allow the bao buns to cool slightly then slice in half and fill with Cricket St Thomas brie, bacon, and cranberry sauce. Place in a sandwich toaster until the cheese is melted and enjoy.
