These are the best all purpose bowls for a multitude of applications. Choose a wide range of sizes (be sure to get a large bowl for whipping egg whites and whipped cream). In general, the heavier the bowl, the higher quality.

When shopping for a new washer, look for a front loading (horizontal-axis) machine. This machine may cost more to buy but uses about a third of the energy and less water than a top-loading machine. With a front loader, you'll also save more on clothes drying, because they remove more water from your clothes during the spin cycle. Look for the Energy Star label.

Modern appliances reach higher temperatures quicker - and often hold heat longer. To avoid worktop damage, follow both the appliance manufacturers instructions and these rules:

• Always use the correct size of pan for the burner, placed centrally. An overhanging pan can scorch surrounding surfaces. Don't use two burners as one (e.g. for a large griddle) - it has the same effect.
• To reduce heat, turn the burner down instead of pulling the utensil partially off the heat source.
