Ingredients (serves 6 | makes 6 Bowls)

• 2 kg Beef Knuckles or Beef Leg Bones
• 4 litres Cold Water
• 2 medium Onions, peeled and quartered
• 4 inch Piece of Ginger, peeled and halved lengthwise
• 20 Dilmah Moringa, Chilli, Cocoa and Cardamon Tea Bags
• 1.5 tbsps Salt
• 1/4 cup Fish Sauce
• 2 tbsps Cane Sugar
• 1 packet 'Banh Pho' Noodles
• 300g Round, Sirloin or Tri-TipSteak thinly sliced across the grain
• 1 Medium Red Onion, thinly sliced in full circles
• 1/4 cup Coriander Leaves
• 1/4 cup Thai Basil Leaves

Method

1. Parboil Bones: Add beef bones to a large pot that will hold at least 10 litlres. Then, cover bones with cold water. Place pot onto high heat and bring to a boil. Boil for 3 to 5 minutes. During this time, impurities and foam (or scum) will be released and rise to the top.
2. Drain bones, discarding the water. Then, rinse bones with warm water and scrub stockpot to remove any residue that has stuck to the sides. Add the bones back to the stockpot and cover with 3 litres of cold water.
3. Char Onion and Ginger: Move an oven rack to a high position then turn grill to high. Line a baking sheet with aluminum foil.
4. Place quartered onions and halved ginger onto baking sheet then grill for 10 to 15 minutes, turning onions and ginger occasionally so that they become charred or browned on all sides.
5. Tie the tea bags together with butchers twine to seal.
6. Simmer Broth: Bring stockpot with parboiled bones and water to a boil then lower to a gentle simmer. Add charred onion and ginger as well as the tea.
7. Add 1.5 tablespoons of salt, a 1/4 cup of fish sauce and the cane sugar.
8. Continue to simmer broth for 3 hours. If at any time foam or scum rises to the surface, use a spoon to remove it.
9. Strain Broth: Use tongs or a wide mesh spoon to remove bones, onion and ginger from broth then strain broth through a fine mesh strainer.
10. To Serve: Divide the beef, noodles and red onion between the bowls and pour piping hot broth over and allow to sit for 3 minutes. Top with fresh coriander and thai basil leaves.
