Blast Chilling
Blast chilling is a professional food preparation method used in restaurants and food service to quickly and safely cool cooked foods. It's like a super-powered cooling process that brings hot food to safe storage temperatures much faster than regular refrigeration. This technique is important in commercial kitchens because it helps prevent bacteria growth, maintains food quality, and follows food safety regulations. Chefs use blast chillers, which are special high-powered cooling units, different from regular refrigerators. This process is especially common in high-end restaurants, catering companies, and industrial kitchens where large amounts of food need to be prepared in advance.
