You can store any leftover cheese ball pieces in an airtight container in the fridge at 37°F for up to four days. Wrap the exposed edges tightly with plastic wrap before popping the lid on so the cream cheese doesn't absorb funky fridge smells. Don't freeze the leftovers once they're rolled in the toppings because the pecans get soft and the parsley turns slimy when it thaws. When you want to eat them the next day, just grab the container and let it sit on the counter for 10 minutes to take the chill off. If the coating lost its crunch, just scatter a tablespoon of fresh crumbled bacon over the top to bring back that texture. Give it a quick sniff for any sour aroma or surface moisture before diving in, since those are dead giveaways that the dairy went bad.
