State Why is necessary to defrost foods before cooking?

Defrosting foods before cooking is necessary to ensure even cooking and to prevent the growth of harmful bacteria. When food is frozen, ice crystals form, which can lead to uneven heating; cooking frozen food can result in the outer layers being overcooked while the inside remains frozen. Additionally, defrosting allows for better flavor and texture in the final dish, as it helps retain moisture and prevents the food from becoming tough. Proper defrosting methods, such as in the refrigerator or using cold water, also help maintain food safety.
