How do you keep your food cold when you don't have a refrigerator? We came up with a whole list of ideas .
Sprinkle salt over your ice. The chemical reaction will slow down the melting process. Dry ice will not “melt” and water down your food, but isn’t a long-term solution.
Build a shelf or using a cooking rack to keep all the food you don't want to get wet above the ice.
Use jars – try putting everything, meat cheese, condiments, etc. in wide-mouth, quart canning jars with lids.
Use two different coolers; take a “dinner” cooler and a “drink” cooler. Make sure they are both labeled, so no one opens the dinner cooler for anything because they can easily find their drinks.
