When choosing a bowl for your potato salad, you need to keep some important properties of potato salad bowls in mind. Different bowls have different designs that make some better suited to storing potato salad than others. For example, a higher quality bowl might have been manufactured to a higher standard than a subpar bowl. You might also want to choose different bowls depending on the amount of potato salad you want to prepare. There are bigger bowls and smaller bowls, differing in size and thus in the amount of potato salad they can accommodate. A smaller bowl is great when you're aiming to cook for just a few people, while a larger bowl is ideal for bigger groups. Brand name bowls like the classic SALADBOWL(tm) are preferred by some potato salad fans, while others appreciate the great price offered by newer, less established brands. Keep in mind that while a cheaper bowl is more affordable, it can also break more easily, so it's not a bad idea to compare the warranty period offered by different manufacturers.
