Spicy Firecracker Beef

Step 1: Mix the soy sauce, rice vinegar, sriracha and brown sugar in a small bowl. Set aside.

Step 2: Heat the oil in a large frypan over high heat. Add the beef and cook, breaking it up as you go, until no raw meat is visible, about 2½ minutes. Add the garlic and chilli flakes and cook for 1 minute.

Step 3: Add the prepared sauce and stir to coat the beef. Cook for 5 to 7 minutes, stirring only every minute or so at first and then more often toward the end, until the sauce reduces and the beef starts to caramelise. Let it caramelise well for good flavour.

Step 4: Add the water and cook for 1 minute to make the beef saucier.

Step 5: Serve over rice, sprinkled with sesame seeds and green onion, with a squeeze of extra sriracha if you like. Add vegetables on the side.
