When you want 1 cup of liquid to be fairly thick, it takes 1 tablespoon of cornstarch. (A stir-fry sauce might use only 1-2 teaspoons per cup of liquid). It will take about 3 tablespoons of flour to replace 1 tablespoon of cornstarch, and you will need to cook the sauce for much longer to get rid of the raw flavor of the flour. Flour is a very stable thickener, but will not result in the same glossy shine that cornstarch produces. Arrowroot, on the other hand, makes a beautifully shiny sauce and may be substituted in an equal or slightly greater amount, but will need to be cooked a little longer than cornstarch. For other substitutes like potato flakes or granules, tapioca and rice starch, 2 teaspoons will likely thicken about as much as 1 tablespoon of cornstarch.
