ANSWER: Authentic holy basil stir-fry (*pad krapow*) hinges on peppery holy basil, fiery chilies, and a crispy-edged fried egg.
When ordering from a Thai menu, look for dishes made with true bai krapow (holy basil) rather than sweet Thai basil for that signature clove-peppery heat. A quality version generally runs $14 to $20 and should have noticeable wok char and a runny kai dao (fried egg) on jasmine rice.
If you were looking for the menu of a specific restaurant named Holy Basil, which city or neighborhood are you in?
