Place the consommé, water, ginger, cinnamon stick, star anise, cardamom pods, coriander seeds and fish sauce in a saucepan. Bring to the boil, reduce the heat to a simmer and cook for 10–15 minutes or until aromatic.
Meanwhile, place the noodles in a heatproof bowl, pour boiling water over them and allow to sit for 5 minutes, or until cooked. Drain.
Place separate piles of the herbs, bean sprouts, chilli and lime onto a platter or large plate, and the hoisin sauce in a small bowl.
Once the fragrant stock is ready, strain, then return to the pan and bring back to the boil. Place the meat into the hot stock, stir and remove from the heat as soon as it is cooked — this will happen quickly. Divide the noodles among four large bowls, piling the beef on top. Ladle over the hot stock. Allow each guest to help themselves to the accompaniments. Serve immediately.
