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 4–5 minutes. Remove and let cool.
03 - Finely chop the charred scallions and set aside.
04 - In a medium bowl, combine the sour cream, cream cheese, mayonnaise, grated garlic, soy sauce, sesame oil, lime juice, salt, and pepper. Mix until smooth and well blended.
05 - Stir in the chopped charred scallions and 2–3 tablespoons of chili crisp, adjusting the quantity to your preferred heat level.
06 - Transfer the dip to a serving bowl. Swirl extra chili crisp on top and sprinkle with chopped cilantro and toasted sesame seeds if desired.
07 - Serve chilled or at room temperature alongside chips, crackers, or crudités.
