Cornstarch (or corn flour) usually works best with water-based sauces, reduced stock, jus from meats, wine sauces, wine-soy-vinegar Chinese sauces, etc. Make a thin paste of cornstarch and water, and stir that into the very warm liquids in the pot or pan. Over-heating or over-cooking will break down the starches.
