Squeeze any excess water out of the soaked mushrooms and then press firmly with kitchen paper to dry them before finely slicing them.
Mix the stock ingredients together in a jug.
Build Your Wok Clock: Start at 12 o'clock with the stock, followed by the greens, shiitake mushrooms and then the garlic.
Bring the stock to a vigorous boil in a wok, add the greens and boil for 3-4 minutes. Strain through a sieve set over a mixing bowl to reserve the stock.
Return the wok to a medium heat to dry, then add 2 tablespoons of vegetable oil followed by the mushrooms and stir-fry for 2-3 minutes until they begin to crisp up around the edges. Add the garlic and stir-fry on a medium heat for 1-2 minutes until it starts to turn golden brown but not burn. Season with a pinch of salt and pepper and then remove from the heat.
Place the greens on a serving plate, pour over a ladleful of the hot stock and top with the crispy mushrooms and garlic.
