How to Make It
In a blender or food processor, pulse all of the ingredients except the hens until chunky.
In a large bowl, season the hens with salt. Add the marinade and rub it all over the hens and in the cavities. Cover and refrigerate for 1 to 3 hours.
Preheat the oven to 375°. Set a rack over a large rimmed baking sheet. Arrange the hens on the rack, leaving some of the marinade in the cavities. Roast for about 1 hour, or until an instant-read thermometer inserted in the inner thighs registers 165° and the juices run clear. Transfer the hens to a cutting board and let rest for 10 minutes before serving.
