Fat Substitute for Salad Dressings:

    Oil Substitute Mix together in a small saucepan:
    1 cup cold water or light vegetarian broth
    2 tsp cornstarch

    Cook, stirring constantly, over high heat until thickened and clear. This will thicken even more
    when chilled, which is perfectly normal. You can use this in other dressing recipes in place of 
    oil, too.
