We made this for my sister during Thanksgiving 2010. It's absolutely delicious on potatoes and stuffing.
1/2 cup olive oil
1/3 cup chopped onion or shallots
5 cloves garlic, minced
1/2 cup all-purpose flour
4 tablespoons light soy sauce
2 cups vegetable broth
1/2 teaspoon dried sage
1/2 teaspoon salt
1/4 teaspoon ground black pepper
Saute onion and garlic at medium heat, about 5 minutes. Add flour and soy sauce, stirring to form a paste. The paste looks unappetizing and like something went wrong. It's ok; this is supposed to happen.
Whisk in broth gradually.
Season with sage, salt and pepper. Bring to boil then reduce heat. Simmer, stirring constantly, until thickened, about 8 to 10 minutes.
