Elizabeth Brown, author of Perfect Slow Cooking (rrp £6.99; Random House Books), shares these essential tips for slow cookers
Make sure you always set the temperature correctly. If you are in a rush, you may wish to cook things at a higher temperature. If this is the case, you should be aware that the cooking time on ‘high' is just over half of that on ‘low.'
Make sure the slow cooker is positioned on a sturdy surface. You may wish to place it on a tea towel, which will absorb any liquid which spits or spills out. (It's also best to make sure the cooker is not touching the walls or any other appliances due to the heat it produces.)
Choose dried herbs over fresh, whenever possible. Fresh herbs will go brown and limp in the long, moist cooking process. Whole dried herbs and spices will release their flavour over time.
If you have any leftovers, remove them from the pot, transfer them to a clean container, let them cool slightly and then refrigerate and freeze. Don't allow food to cool in the slow cooker itself, as it retains its heat for a long time and bacteria can build up during the cooling process.
Don't be tempted to lift the lid to check on your cooking. The heat loss will extend your cooking time significantly. Every time you lift the lid, you can expect to add 20 to 30 minutes to your cooking time.
