1 cup vegetable oil
3/4 cup white vinegar
9 garlic cloves, minced
1/3 cup oregano leaves, finely chopped
3 tablespoons sweet paprika
3 tablespoons chili powder
1 tablespoon curry powder
Three 3-1/2-pound chickens
PREPARE THE CHICKEN
In a bowl, whisk the oil, vinegar, garlic, oregano, paprika, chile powder, curry and 2 tablespoons of salt. Arrange the chickens in a dish and pour the marinade over the chickens, rubbing it all over the birds. Cover and refrigerate overnight.
Preheat the oven to 400°. Set a rack on a rimmed baking sheet lined with foil. Remove the chickens from the marinade, scraping off any excess.
Roast the chickens for about 1 hour, until an instant-read thermometer inserted in the inner thigh reaches 160, rotating the baking sheet halfway through. Transfer the chickens to a carving board and let rest for 10 minutes.
