To make the chutney, combine all the ingredients in a large heavy
saucepan and bring to a boil. Lower the heat and stirring often,continue
to cook the chutney uncovered, for 1 to 1 1/2 hours, until it begins to
thicken. Take care not to let it boil or bur. When thickened, spoon the
chutney into a bowl or glass jars and allow to cool to room temperature.

Preheat the grill to 400F. Make sure your oven thermometer is inside the
grill. For ideal results it is essential to maintain a constant
temperature throughout the grilling time. Mix together the garlic, onion,
leon and tarragon in a small bowl. Split the mixture, stuff half of it
into the cavity of each chicken. Tie the legs together with kitchen
string to keep stuffing inside the bird.To make the rub, whisk together
the salt, cayenne, oil, and lemon juice in a small bowl and rub this
mixture over the chickens, making sure to coat all sides well. Place the
chickens, side by side, breast side down, in a grill pan. Grill the
chickens with the lid closed, at 400F for 40 minutes.After the first 10
minutes, check the temperature. The roasting temperature must remain at
400F throughout the entire roasting time. After 40 minutes, turn the
chickens on their backs and grill 40 minutes longer. Test for doneness by
inserting an instant read thermometer into the thigh, not touching the
bone. It should read 165F. Transfer chicken o a platter and cut into
service size pieces. Serve the plum chutney on the side.
