Cornstarch should be added at the end of cooking. First, mix it with a small amount of cold water to create a slurry. Then, gradually stir it into your hot liquid, allowing it to thicken while stirring continuously. This ensures a smooth and lump-free texture in dishes like sauces, soups, and gravies.

FAQs & Answers

  1. Why should cornstarch be mixed with cold water before adding? Mixing cornstarch with cold water creates a slurry that prevents clumping and ensures even thickening when added to hot liquids.
  2. Can cornstarch be added at the beginning of cooking? No, adding cornstarch too early can break down its thickening ability; it’s best added near the end of cooking.
  3. How long does it take for cornstarch to thicken sauces? Cornstarch thickens sauces almost immediately after it reaches a boil, usually within 1-2 minutes while stirring.
