frozen

Frozen refers to food products that have been subjected to temperatures at or below 0°C (32°F), causing the water content to crystallize and halting microbial growth and enzymatic activity. Freezing is one of the oldest and most effective methods of food preservation, applicable to virtually all food categories including produce, meat, seafood, dairy, and prepared dishes. The process can occur through mechanical freezing (blast freezing, contact freezing) or natural freezing, with commercial frozen products typically reaching -18°C (-0.4°F) or lower for long-term storage.

Frozen ingredients are foundational to modern cooking, offering year-round access to seasonal produce, convenience, and extended shelf life without significant loss of nutritional value. Frozen vegetables, fruits, and seafood are staples in both home and professional kitchens, often preferred for their consistent quality and reduced preparation time. Frozen items are used in soups, stews, stir-fries, baked goods, smoothies, and prepared meals. Proper thawing methods—refrigerator thawing, cold-water thawing, or cooking directly from frozen—are essential to maintain texture and food safety. Flash-frozen products preserve quality better than slowly frozen items.
