Ease of cleaning is well worth considering at the outset. Stay clean liners resist dirt build-up but pyrolitic cleaning is the ultimate. It burns off all baked-on debris at 500°C so that all you have to do is sweep out the resulting ash. Look out for ovens with a steam cleaning facility, too, and remember that some ovens have removable inner doors that are easy to clean.

While some may consider this a bit on the gadgety side, I think it is a must as dressings do not stick to water-logged salad greens.

The insulation on electrical cords can become damaged by wear, flexing, or age. Do not use any cord that is stiff or cracked. Some clues that you may have an electrical problem are:

• Flickering lights. If the lights dim every time you turn on an appliance that circuit is overloaded or has a loose connection.
• Sparks. If sparks appear when you insert or remove a plug, they could be a sign of loose connections.
• Warm electrical cord. If an electrical cord is warm to the touch, the cord is underrated or defective.
• Frequent blown fuses or broken circuits. A fuse or circuit breaker that keeps tripping is an important warning sign of problems.
• Frequent bulb burnout. A light bulb that burns out frequently is a sign that the bulb is too high a wattage for the fixture.
