Roasted Sweet Onions with Balsamic Vinegar

2 Sweet Onions
2 1/2 tablespoons balsamic vinegar
2 1/2 tablespoons water
2 tablespoons extra virgin olive oil
1/2 teaspoon salt
1 dash pepper, to taste
4 sprigs fresh thyme
2 tara cotta onion roasters

Cut off tops of onions, remove skins keeping root end intact. Slice the
onions into 6 even wedges. Place skin side down in a Terra Cotta Roaster.

In a small bowl, combine vinegar, water and oil.

Pour the mixture over the onions and sprinkle with the salt and pepper. Tuck the thyme sprigs in among the onions. Cover and place the roaster in a cold oven. Roast at 400 degrees for 45 minutes, basting occasionally, until tender.
