Tips for Keeping Your Buffet Menu Cool and Safe
Keeping buffet food cold isn't just a matter of taste, it's also an important safety practice. Cold buffet food that isn't kept cool enough can grow harmful pathogens, creating the risk of food poisoning sickening your guests. It's especially important to keep proteins cold, so pay special attention to meats, beans and dairy products. But even seemingly safe foods such as rice and cooked vegetables can grow dangerous bacteria if you keep them for too long in the unsafe temperature range, which is between 40 degrees and 140 degrees Fahrenheit.
Ice is an easy and readily available way to keep your buffet food cool.
Using Ice in a Buffet
The ice you use to keep your buffet food cool shouldn't be in direct contact with the food. Instead, arrange ice in a separate bowl or pan and then place the container or dish with your buffet items into the bowl holding the ice. You can even purchase combination containers made specifically for this purpose.
If you're serving finger food on a platter, use a shallow pan as wide as the platter, and fill the pan with ice. Use crushed ice if possible, so you can distribute it well; even if you're using ice cubes, make sure they haven't frozen together into chunks that will make your food bowls or platters sit awkwardly. If you're placing a bowl with food inside a bowl of ice, make sure the ice is filled up to the level of the food. Use metal or Pyrex bowls for your food, because these materials will hold and transfer the cold from the ice most effectively. Check the ice levels often, especially on hot days, and replenish the ice as needed.
Other Strategies for Keeping Buffet Food Cold
Instead of heaping your buffet bowls or platters with salads and finger food that you'll need to keep cold, hold most of your food in a refrigerator or ice chest, and put out a little at a time. It's easier to manage the temperature of a small bowl of food than a large one, even though it takes a bit of extra work to replenish more often. If you're refilling platters, move the items that have been sitting out longest to the spots where guests will reach for them first, such as the top of a stack or the section of the platter closest to where guests come through the line and serve themselves.
Very Hot Days
The hotter the day, the more difficult it will be to keep your buffet food cold. Pay extra attention to ice and temperatures during the height of summer, and provide shade for the food too, if possible.
