Cooking Instructions
1. Make Toasted Rice Powder
[]  Place uncooked rice in a dry pan over medium heat.
[]  Toast the rice, stirring constantly, until golden brown and fragrant. Be careful not to let it burn.
[]  Once toasted, remove from heat and let it cool slightly.
[]  Transfer to a mortar and pestle, and pound until it reaches a coarse, sandy texture with some gritty bits for added crunch and aroma.
2. Cook the Beef
[]  If refrigerated, bring the steak to room temperature at least 30 minutes before cooking.
[]  Season both sides generously with salt and pepper.
[]  Preheat your charcoal grill or a stainless steel pan over medium-high heat until very hot. 
[]  Grill or sear the beef for 2–3 minutes per side for medium-rare to medium doneness. Target internal temperatures: Medium Rare: 54–57°C (130–135°F) or Medium: 60–63°C (140–145°F).
[]  Let the beef rest for 5 minutes, then slice thinly against the grain.
3. Prepare the Dressing
[]  In a mixing bowl, combine fish sauce, lime juice, palm sugar, and chili flakes.
[]  Stir until the palm sugar dissolves.
[]  Add thinly sliced shallots, fresh mint leaves, chopped spring onions, sawtooth coriander, and the toasted rice powder. Mix gently to combine.
4. Assemble the Salad
[]  Add the sliced steak to the dressing and herb mixture.
[]  Toss everything well until evenly coated.
[]  Taste and adjust the seasoning as needed. The flavor should be a bold balance of spicy, sour, and salty.
5. Serve
[]  Transfer to a serving plate.
[]  Garnish with extra mint leaves on the side.
[]  Serve immediately as part of a Thai meal with sticky rice and fresh vegetables.
