Acidic items like Asian sweet and sour sauce or other sauces with a delicate tastes you can substitute arrowroot flour at a 1:1 ratio. Works best in egg based recipes but poorly with dairy based sauces
In gravies you can substitute 1 T cornstarch with 2 T flour. But you must cook your savory sauce or gravy an additional 4-5 minutes for the thickening agent to work without leaving a flour taste.
