You may want to wait until the last minute to arrange your charcuterie board, but you can slice the cheeses a few hours before and store them in the fridge, wrapped in plastic wrap, with the meats and sliced fruits or veggies. Spoon the jam, honey, or any other condiments into their small bowls, cover them in plastic wrap, and store them in the fridge as well. When ready to serve, let the cheese, honey, and jams come to room temperature. Bring out any of the deli meats last and layer your platter right before you want to serve your guests.
