By law manufacturers must disclose the energy efficiency of their appliances, rated A to G. These are usually displayed prominently in showrooms. The better the rating, the more energy efficient the appliance is - good for both the environment and your pocket.

Many still consider a whip as a "gourmet" piece of kitchen equipment. Nothing could be further from the truth. It is as essential as a kitchen stove and should be in everyone's kitchen. Nothing works better for mixing a multitude of different preparations or for making sauces or gravy. Buy a solid stainless steel whip with moderately stiff wires. Very thin wires are for mixing delicate things like egg whites or whipped cream. Very thick, solid wires are for mixing stiff dough.

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.
