Small appliances are defined as those that are fully made, charged, and hermetically sealed in factories with five pounds or less of refrigerant, such as refrigerators and freezers, medical or industrial research refrigeration equipment, room air conditioners, and other products. For many home cooks, the time savings provided by simple kitchen tools is their main advantage. The cook gets back what they value most: their time, thanks to modern appliances. Tuna salad can be made in a matter of seconds in a food processor rather than over the course of ten minutes. Small but essential kitchen equipment are becoming easier to find, better made, and more high-tech every day. Because of this, even entry-level products are much more reliable than they ever were.
