1. Step
Whisk coconut milk, curry paste and garlic powder in a large saucepan. Add eggplant and scallions; bring to a boil over high heat. Reduce heat to maintain a simmer, cover and cook for 6 minutes. Add shrimp, cover and continue cooking until the shrimp are just cooked through and the eggplant is tender, about 4 minutes more. Stir in basil (and/or cilantro) and serve with lime wedges, if desired.
