As a general rule of thumb, you want to make sure that you get the food in your box inside your refrigerator within 24 hours of it landing on your doorstep. Based on personal experience, I’ve found that the ingredients will stay cool for a bit longer than that. A lot of this will depend on the temperature in your area. As long as the most perishable items (meat and fish) are cool to the touch when you take them out of the box, the ingredients should still be safe to use. If they aren’t, be sure to contact Home Chef as soon as possible.
