• 1 bunch coriander
  • 3cm piece ginger, finely grated
  • 2 cloves garlic, thinly sliced
  • 4 long red chillies, seeded, thinly sliced on the diagonal
  • 2 lemons, zested, juiced
  • 2 tablespoons fish sauce
  • 55g (1/4 cup firmly packed) brown sugar
  • 700g beef sirloin, cut into 1cm x 4cm strips

  • 1 Lebanese cucumber, halved, seeded, thinly sliced
  • 1 cup mint leaves

  • Step 1 To make nam jim, trim roots from coriander and rinse well. Pick leaves and reserve. Process coriander roots, ginger, garlic, half the chillies, lemon zest and juice, fish sauce and brown sugar in a food processor until well combined and finely chopped.
  • Step 2 Combine half the nam jim with beef in a large bowl, cover and refrigerate for 30 minutes to marinate.

  • Step 4 Place onion, cucumber, reserved coriander leaves, mint, remaining chillies, beef mixture and remaining nam jim in a large bowl and toss to combine. Season with salt and pepper, scatter with peanuts and serve with rice stick noodles, if using.
