Slow cooker reviews: Features explained
Slow cooker size
Slow cooker sizes vary. The largest have 6-litre cooking pots with a useable volume of 4.5 litres. This can contain enough stew for six to eight adults.
Common smaller sizes include 3.5 litres cooking pots with a useable volume of 2 litres. These are large enough to feed at least two people.
Oval slow cookers vs round slow cookers
Round slow cookers are best for cooking stews or curries.
Oval slow cookers are the most common bowl shape available and can also accommodate joints of meat for roasting.
Slow cooker settings and functions

Cooking on this setting can take 10 to 12 hours.
Med (medium) setting
Use the medium setting for cooking cuts of red meats.
This setting is useful for cooking faster without losing all the slow cooking benefits, but the results won’t be as impressive as cooking on low for longer.
Hi (high) setting
This is recommended for cooking pale meat such as chicken. It cooks the meat faster (in three to six hours) and at a slightly higher temperature.
A keep warm or hold setting prevents food drying out if your diners are delayed, but stops it getting cold.
Other slow cooker features to look for
Not all models have a timer, but it's useful if you are going to be away from the slow cooker for longer than the recipe states.
'On' indicator light
An indicator light is a good visual indicator that your slow cooker is working. This is useful as they take a while to warm up and you won’t be able to tell straight away that cooking has started.
Extension leads are dangerous, as liquids can be easily spilt into them. Make sure your slow cooker cord will easily reach.
Check your instructions. For some, only the lid is dishwasher proof. If your cooking pot isn’t dishwasher safe, fill it above the cooking line with warm water and a dash of washing up liquid. Burnt-on remains should just slide off with minimal soaking.
