While there isn’t too much to worry about if you are packing a cooler with beers or soda, packing a cooler with any or all perishable food that you plan to eat for the next few days can take a bit more planning. Start by putting any freezer packs that you intend to use at the bottom of the cooler. Next, add in items that you’d like to keep as cold as possible and that are unlikely to leak or spill—milk cartons, sodas, or beers. You can also add meat to this layer, but be sure that it is tightly wrapped (ideally vacuum sealed). Add in a layer of ice here (if desired), and then pack on top fruits and vegetables that can sustain or respond well to freezing temps, such as blueberries or root vegetables (less accommodating produce can be placed on top of that). Utilize the pull-out drawer for your squishiest items, such as butter and cheese.
