The cooler corn hack might be tempting to anyone preparing for a large group of people. The hack uses a large cooler that is filled with shucked ears of corn. Then, boiling water is poured over the corn and the cooler is closed and left to cook for 30 minutes. It’s a seemingly efficient way to prepare large amounts of corn.
Herve Malivert, Director of Culinary Affairs at the Institute of Culinary Education, however, warned Today that the method wasn’t safe. Plastic coolers can start to degrade over time when exposed to those high temperatures, and since the plastic can be easily scratched, foodborne pathogens might grow within the cooler. Additionally, leaving boiling water to sit will result in a temperature drop below 136 degrees Fahrenheit, reaching a dangerous range where bacteria quickly starts to multiply.
