How to Make It
Preheat grill to high (450°F to 500°F). Place cheese in bowl of a food processor; pulse 5 times. Add sour cream, mayonnaise, cilantro, calamansi juice, togarashi, and garlic to food processor; pulse until mixture just comes together but still has some texture, about 10 times. Transfer to a large bowl.
Place corn on oiled grates; grill, covered, until lightly charred on all sides, about 8 minutes. Transfer corn to bowl with cheese mixture; turn to coat. Transfer to a serving platter; sprinkle with aonori, and serve with calamansi halves.
