The main idea is rapid, two-stage cooling to keep food out of the danger zone where pathogens multiply. The standard sets a two-step path: first cool from 135°F down to 70°F within 2 hours, then from 70°F to 40°F (or colder) within the next 4 hours. This plan minimizes the time food spends between 135°F and 40°F, where bacteria grow quickly, by pushing it quickly through the 135°F–70°F range and then continuing to chill to safe refrigeration.

The option that matches these exact temperatures and times is the best choice because it follows the recommended two-stage cooling pace: fast reduction to 70°F in 2 hours, then a further drop to 40°F within 4 more hours. Starting at a different temperature, ending at a different target, or using a different total timeframe would not align with this guideline and could leave the food in the danger zone too long.
