In a small frying pan set over medium heat, toast rice for 3 to 5 minutes, stirring frequently, until browned. Transfer to a small bowl and set aside to cool. Using a pestle and mortar, grind to a fine powder. Set aside.
2Heat oil in a cast-iron frying pan over high heat, until it barely begins to smoke. Add pork and sear for 3 to 4 minutes, until the bottom is crisp. Using a spatula, break up the meat, add shallots and half of the Thai chiles, and sauté for 2 to 3 minutes. Turn heat down to low.
3Stir in togarashi and the ground glutinous rice and cook for 30 seconds. Add yuzu juice, fish sauce, and sugar and stir until the sugar dissolves. Add mint, cilantro, and half the scallions.
4Arrange lettuce leaves on one side of a serving plate and spoon pork larb mixture onto the other side. Arrange remaining chiles and scallions off to the side of the plate. Spoon pork larb onto a lettuce leaf, garnish to taste with chiles and scallions, fold up, and enjoy.
