Preparation:
Place onion wedges in baking dish. Drizzle with oil and sprinkle with just a little salt. Stir to coat all pieces evenly. Roast onions, uncovered, at 350F until browned and soft, about 1 hour. Remove and let stand until slightly cooled. Put onions in blender along with broth and soy sauce and blend to smooth puree. Transfer sauce to small saucepan or microwavable dish, cover and set aside. |
