Blanching 🔊
Meaning of Blanching
Blanching refers to briefly immersing food (usually vegetables or fruits) in boiling water and then rapidly cooling it in ice water to halt the cooking process. It is used to preserve color, texture, and nutrients.

Example of Shocking
- After blanching the asparagus, shocking it in ice water keeps it crisp and bright green.
- Shocking is essential in professional kitchens to maintain vegetable quality.
Steaming 🔊
