Preheat oven to 350°.
Peel onions, and cut in half crosswise. Place onions, cut sides down, in an 8-inch square baking dish; drizzle with water. Cover with foil; bake at 350° for 30 minutes.
Combine honey and remaining ingredients. Turn onions over; brush half of honey mixture over onions. Bake, uncovered, an additional 30 minutes or until tender, basting with remaining honey mixture after 15 minutes.
