Andrew Swallow, author of Mixt Salads: A Chef's Bold Creations and founder of Mixt Greens, wants to help you avoid the "lipstick" problem that your average 3-to-1 ratio for vinaigrette presents. All that oil equals shiny, shiny lips. Instead, trying making a vinaigrette with a 2-to-1 or even 1-to-1 ratio. It'll bring out the flavor of your salad's ingredients better and won't oil up your face.
