Thai Pork Larb Salad

¾ pound lean pork or chicken, trimmed of connective tissue and cut into 1-inch cubes
½ cup equivalent Thai Toasted-Rice Powder (determine volume and amend)
½ cup thinly sliced shallots
½ cup vegetable oil
¼ cup fish sauce
2 scallions, thinly sliced
½ cup roughly chopped fresh basil leaves (preferably Thai)
½ cup roughly chopped fresh cilantro leaves and tender stems
¼ cup roughly chopped fresh mint leaves
2 tablespoons ground dry Thai chiles (more or less to taste)
¼ cup lime juice from about 4 limes
2 tablespoons palm sugar (see note)
Crumbled pork rinds (optional)
Thinly sliced fresh red chile (optional)

Place meat on a tray leaving a 1-inch space between each cube and place in freezer until firm but not frozen, about 15 minutes. Transfer half of meat to bowl of food processor and pulse until meat is roughly ground and no pieces larger than 1/4-inch remain, about 10 one-second pulses. Transfer meat to a bowl. Repeat with remaining meat. Set aside.
While meat chills, place rice in an empty 12-inch skillet and heat over medium-high heat shaking constantly until rice is golden brown and a nutty popcorn-like aroma emerges, about 6 minutes. Transfer to mortar and pestle and grind until it has the texture of coarsely ground black pepper. Alternatively, grind in a spice grinder. Set aside.
Add oil and shallots to now-empty skillet and cook over medium-low heat, stirring constantly until shallots are golden brown, about 5 minutes. Drain shallots and discard oil but do not wipe out pan.
Add pork, 1 tablespoon fish sauce, and 2 tablespoons water to pan. Cook, stirring frequently until pork is just cooked through but not browned at all, about 6 minutes. Transfer to a large bowl and allow to cool 5 minutes. Add remaining fish sauce, scallions, basil, cilantro, mint, half of chile, lime juice, sugar, and toasted rice powder. Toss with hands and taste for seasoning, adding more chile if higher heat is desired.
Just before serving, add Fried Shallots and toss again. Garnish with pork rinds and chile. Serve immediately with cabbage or lettuce on the side.
