Which is the proper procedure for delivering prepared hot food off-site? 1. drive to the off-site location as quickly as possible. 2. cook all fresh foods at the point of delivery. 3. reheat the food to 165 f. immediately upon arrival. 4. maintain hot food temperatures above 135 f?

From the choices, I think the correct answer would be option 4. The proper procedure for delivering prepared hot food off-site would be maintain hot food temperatures above 135 degrees Fahrenheit or 57 degrees Celsius. At this temperature, you would be able to deliver the food still warm while making sure that it is cooked enough, not under or over cooked. This temperature is a fair enough level to be able to ensure  that the delivered food is not cold and would still be like as if it was cooked recently.  Also, along with maintaining this temperature, it would be best to deliver it very fast to the customer.
