culinary-engineer
A person of culinary background, employed by frozen food companies to experiment and determine the appropriate cooking temperatures, times and microwave wattages to achieve optimal results without putting consumers health at risk.
Ever wonder why they set a certain temperature for the oven and the times, and why you must have a certain wattage microwave to cook certain meals? Well, I believe this culinary-engineer is the one who after many trials and tribulations comes to the conclusion of the precise combination of temp and time that these meals must be prepared.
