Yes, you should always mix cornstarch with cold water before adding it to your hot liquid. This mixture, called a slurry, helps prevent clumping and ensures the cornstarch can be evenly distributed, leading to a smoother and more consistent thickening.

FAQs & Answers

  1. Why should cornstarch be mixed with cold water before adding to hot liquids? Mixing cornstarch with cold water creates a slurry that prevents clumping and allows even distribution for smooth thickening.
  2. What happens if you add cornstarch directly to hot liquids? Adding cornstarch directly to hot liquids can cause it to clump, resulting in a lumpy texture and uneven thickening.
  3. Can warm water be used instead of cold water to make a cornstarch slurry? Cold water is best because it prevents premature gelatinization; warm water might cause lumps before mixing into hot liquids.
