During the holidays, people tend to spend more money for specialty meats and roasting is a recommended method for cooking tender meats that will make a lasting impression on your guests. To keep the meat tender and minimize shrinkage due to the evaporation of moisture, an oven temperature of 325 °F should be used. It is not recommended to cook meat and poultry at oven temperatures lower than 325 °F because these foods could remain in the "Danger Zone" (temperatures of 40 to 140 °F) too long and allow bacteria to multiply rapidly and cause foodborne illness.
