01 - Set a grill pan or skillet over medium-high heat and allow it to become thoroughly hot.
02 - Place the trimmed scallions on the hot pan and cook, turning occasionally, until deeply browned in spots and softened, about 4 to 5 minutes. Remove from the pan and let cool.
03 - Once cooled, finely chop the charred scallions and set aside.
04 - In a medium mixing bowl, combine the sour cream, cream cheese, mayonnaise, grated garlic, soy sauce, sesame oil, lime juice, salt, and pepper. Stir until completely smooth and well blended.
05 - Gently stir the chopped charred scallions and 2 to 3 tablespoons of chili crisp into the dip base, adjusting the amount to your preferred heat level.
06 - Transfer the dip to a serving bowl. Swirl additional chili crisp over the top and sprinkle with chopped cilantro and toasted sesame seeds if desired.
07 - Serve chilled or at room temperature alongside chips, crackers, or crudités.
