Breads and muffins do not need to be refrigerated, but you will still want to put them in a display case to help keep them fresh and free from pests or airborne contaminants. Refrigerated units are ideal for displaying cakes, pies that contain eggs or dairy and other baker’s delights that are best served cold. Whichever type you need, you will want to consider the overall size, number of shelves and service style.
