Bish, afternoon.... It's been said, "Never partially cook any meat, refer, and finish cooking at a different time"...
The reason.... Bacteria starts to grow during the first cook.... continues to grow during the cool down.... Starts to grow again during the reheat and finish cook cycle... The bacteria could have multiplied 100,000 or 5,000,000,000 times during those heating cycles... depends on moisture, and temperature and what ever else makes the specific food pathogen happy..... That is the reason for the 4 hour rule.... Start the cook and get to above the kill temperature for food borne pathogens to complete the cooking cycle.....
