Mix the mayonnaise, honey, onion, paprika, pepper and salt together and let stand at room temperature for 30 minutes. Using a pastry brush, coat each broiler inside and out with the flavored mayonnaise. Place the broilers skin side down on the rack of the broiler about 25 cm away from the heat. Baste frequently during the first 20 minutes of broiling. Turn the chicken over, breast side up, and continue to broil and baste for an additional 25 minutes, or until the breast can easily be pierced with a fork and it is golden brown.
