Heat 1 tbsp of sunflower oil in a wok over a medium heat. Add the tofu and cook for 5 minutes, turning over frequently. Next add the porcini and oyster mushrooms, ginger and garlic and stir fry for a couple of minutes.
Heat a non-stick pan. Heat some oil over medium heat. Once hot, add in the garlic. Sauté until lightly brown and then add in the mushrooms. Pour in the hoisin sauce and maple syrup or other sweetener. Mix well and cook over medium heat for 5-6 minutes or until the mushrooms are cooked through and release some water.
Leave the buns to rest in a warm place to proof for about 30 minutes. During this process, they’ll grow a little bigger (but won’t double) and become plumper (the surface of the wrappers looks tighter and smoother). Now, let’s cook! Bring water to a full boil in a wok/pot. Then place in the steamer basket.
Prepare the filling: In a large pan with high sides, cook the whites of the green onion, shallots and onions with 2 tbsp of oil for a minute or two over medium-high heat. STEP 2. Turn the dough out onto a lightly floured surface, and knead for 6 minutes, until the dough is soft, smooth and bouncy. Add an extra tbsp of water if the dough feels stiff or dry. Place the dough into a lightly oiled bowl, cover with a damp tea towel and leave to rise until doubled in size - around 1.5-2 hours. 1WDRk.
