01 - Set a grill pan or skillet over medium-high heat and allow it to become fully hot before adding the scallions.
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 from the pan and let cool until comfortable to handle.
03 - Finely chop the cooled charred scallions into small, even pieces to distribute throughout the dip.
04 - In a medium mixing bowl, combine the sour cream, softened cream cheese, mayonnaise, grated garlic, soy sauce, sesame oil, lime juice, salt, and pepper. Stir until completely smooth and well blended.
05 - Gently fold the chopped charred scallions and 2–3 tablespoons of chili crisp into the dip base, adjusting the amount of chili crisp to your preferred heat level.
06 - Transfer the dip to a serving bowl. Swirl additional chili crisp across the top and sprinkle with fresh cilantro and toasted sesame seeds if desired.
07 - Serve chilled or at room temperature alongside chips, crackers, or crudités.
