Bring a large pot of water to boil, add the carrots and parboil for 5 minutes.
Drain and rinse with cold water.
In a large glass dish, combine the remaining ingredients.
Add the carrots and marinate for 30 minutes.
Prepare an outdoor grill with an oiled rack set 4 inches from the heat source. Using a oiled wire hinged vegetable basket or just directly on the rack ( whichever you find easier), grill the carrots, turning constantly for a total of 10 minutes, until slightly charred.
