Keen cooks may want to take advantage of multi-function ovens - usually aimed at the top end of the market. As well as traditional cooking, fan or fan-assisted cooking and grilling, these ovens offer up to nine further functions. These include: Top element only (browning), bottom element (final cooking of pastry dishes or pizzas), fan and bottom element (delicate cooking), fan only (thawing).

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.
