How to Make It
Combine stock, coconut milk, lemongrass, and ginger in a medium saucepan. Cover and bring to a boil over high. Reduce heat to medium-low, and simmer 15 minutes. Remove from heat, and let stand 10 minutes. Pour through a fine-mesh strainer, and discard solids.
Return coconut milk mixture to pan; bring to a boil over high. Stir in mushrooms, sambal oelek, lime juice, fish sauce, and honey. Reduce heat to medium, and simmer until mushrooms are tender, 5 to 7 minutes. Remove from heat, and immediately stir in scallops, 2 tablespoons of the basil, and 2 tablespoons of the cilantro. Divide mixture evenly among 6 bowls, and top with remaining 2 tablespoons each basil and cilantro. Drizzle with chili oil, if desired, and serve immediately.
