Arrowroot Starch
Arrowroot has long been used in making clear glazes for fruit pies. Because of its superior thickening ability (use half as much as flour) and clear look, arrowroot is excellent for stir-fry sauce. To thicken sauces or gravies: Use 1-2 tsp. (dissolved in a bit of cool water) per cup. Push food to one side of pan. Tip pan for juices to collect on one side and drizzle in arrowroot-water slurry. Stir over medium heat until slightly thickened, toss to coat food and serve.
