Bottled salad dressing can be convenient but its expensive and often full of salt, sugar, and chemical additives. Making your own is simple and allows you to customize the seasonings to suit whatever meal you are preparing. The amounts given make about 1/4 cup and can be expanded infinitely for larger salads. It can be made several days ahead and kept in the fridge. Sorry about the slightly odd way of putting the ingredients for the creamy dressing variations. The recipe editor is picky about what it will accept.
