The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
"If using frozen meat, allow it to completely thaw in the refrigerator before using," Tiess says. Frozens foods will sit at an unsafe temperature, one that promotes bacterial growth, for far too long.
Packaged foods, when properly stored, can safely be eaten past their "expiration" dates in the US. While some US states regulate expiration dates for some products, generally "use-by" and "best-by" dates are manufacturer suggestions for best quality.

As with all cooked foods, you still need to be mindful of how long you leave the steak out for food safety. “Cooked meat should be refrigerated within two hours of cooking to reduce the risk of ...
Nevertheless, a wide variety of processes have been devised to achieve faster heat transfer from the food to the refrigerant: [8] Air-blast freezing is the oldest and cheapest approach. Food is placed into freezing rooms where the air is cold. Air is either forced ("blasted") onto the food or left static.
Also arrange food evenly throughout a dish to help with cooking. If reheating sauce, soup or gravy, do so in a pan on the stove. Bring liquid dishes to a rolling boil, FoodSafety.gov advises.
Fan ovens cook food faster, and are also used in non-food, industrial applications. Small countertop convection ovens for household use are often marketed as air fryers. When cooking using a fan-assisted oven, the temperature is usually set lower than for a non-fan oven, often by 20 °C (36 °F), to avoid overcooking the outside of the food. [3]
