Crush the black peppercorns into a fine dust using a mortar and pestle. Add the garlic and mash it into a smooth paste. Mix all of this with lime juice, soy sauce, oyster sauce, sugar, and oil in a bowl. Stir well.

Put the steaks in a freezer bag or dish. Pour the marinade over the steaks and toss until they're well covered. Let them sit in the fridge for at least 3 hours or overnight. Take them out 1 hour before grilling to bring them to room temp.

On a high-heat grill, cook the steaks to your preferred doneness with the grill lid open. Avoid pan-searing for too long since the sugar in the marinade can burn.

In a bowl, combine tamarind paste, fish sauce, lime juice, and palm sugar. Stir it around until the sugar is almost gone. Add in the shallots and chili flakes. Let it sit for a bit.

Heat a dry skillet and add uncooked jasmine rice. Stir it nonstop over medium-high heat until it's nice and brown. Let it cool completely, then grind it into a fine but slightly gritty powder using a mortar and pestle or grinder.

Before serving, give your dipping sauce a final stir to make sure the sugar is dissolved. Sprinkle in the rice powder and mint or cilantro, and mix well.

Cut the grilled steak into thin strips. Serve it alongside the dipping sauce and, if you'd like, a side of sticky rice.
