Potato starch has characteristics of being sticky, fine texture and pure white color and comparably poor water absorption. It will condense into transparent sticky semisolid when heated with water. In Chinese cooking(especially Taiwan cuisine), potato starch is usually mixed thoroughly with water and added to other cooked dishes as thickening starch; it will make soup look thick, transparent and shiny. People tend to use corn starch when making pastry because soup thickened by potato starch will easily turn dilute when it cools down; however, soup with corn starch does not change that much when temperature decreases. Besides, it should be noted that potato starch cannot be mixed directly with boiling water or other hot food for it will immediately clot into blocks or chunks.
