from a frozen state. Can I boil frozen chicken drumsticks, without defrosting? When chicken legs are boiled without defrosting, they may cook unevenly. The outside will be cooked and the centre may be just defrosting. When using frozen homemade chicken stock, can I add it frozen to the soup I am making, or do I need to thaw it in the fridge first? The best practice would be to thaw the stock in the refrigerator and reheat it to a piping hot temperature of 74C (165F). The soup once cooked can be stored in the refrigerator for 3 to 4 days. You can freeze it for longer storage and use within 2 to 3 months. I would freeze in individual or meal size servings. Thaw in the refrigerator and reheat only once to a piping hot temperature of 74C (165F). If you cook ground beef patties, then freeze, then heat/cook, is it safe to heat ones that didn't get eaten the next day? No, that is not safe. Reheat only enough patties for that day and leave the rest frozen. By doing this, bacteria that may be in the food will not have the added reheating and cooling time to multiply. How long is a prepared bottle of baby formula good for sitting in room temperature? Is it safe to refrigerate and reheat? Prepared baby formula is a perishable food that requires proper handling.
