Bring a large saucepan of water to the boil. Blanch the ribs for a few minutes. Drain.
Place the ribs in a large saucepan with garlic, ginger and just enough water to cover the contents. Bring to the boil and cook for at least 10 minutes.
Add the lotus root, cover the saucepan and simmer for 30 minutes or until the ribs are tender. Occasionally skim off any scum that forms on the surface.
Season with salt and pepper. Ladle into a big soup bowl then garnish with coriander and serve immediately.
