Here's something I've never made before, or indeed eaten! Pho Bo is apparently a staple Vietnamese soup. Beef stock is made from beef brisket, cinnamon, star anise, ginger, spring onions, fish sauce and salt and pepper. (Some recipes use cardamom, cloves, coriander seeds...) Then, thin noodles and sliced beef (I used the brisket, but you can use thinly sliced raw beef) are placed in each soup bowl and boiling stock poured on top. The diners then get to add their own toppings - bean sprouts, coriander, thai basil, vietnamese mint, sliced red chilli, sliced spring onions, lime wedges. The result is that each mouthful tastes different. Simple but very effective.
