The basil is just barely cooked so that it retains its lively character and color, so make sure to find absolutely fresh leaves for this recipe — nothing limp or beginning to brown. Don't use stems either.
For the marinade:
½ cup fish sauce
½ cup sweet dark soy sauce
2 tablespoons crushed garlic
2 tablespoons freshly grated gingerroot
1 tablespoon freshly ground black pepper
For the stuffing:
½ cup freshly grated ginger
½ cup fresh grated galangal
½ cup sliced bruised lemongrass stalks
½ cup chopped cilantro
½ cup chopped mushrooms
1 roasting chicken, cleaned and patted dry
Picking LemongrassTo choose fresh lemongrass, look for stalks that are firm, full, and pale green. The color indicates freshness. Bend the stalk slightly and smell it. It should be very fragrant.
