Important safety

instructions

The use of any electrical appliance

requires the following of basic common

sense safety rules.

Primarily there is danger of injury or

death and secondly the danger of damage

to the appliance. These are indicated in the

text by the following two conventions:

WARNING: Danger to the person!

IMPORTANT: Damage to the appliance!

In addition we offer the following essential

safety advice.

Your safety

• Never touch the outer enclosure of the

slow cooker during its operation or before

it cools. Do not touch hot surfaces. Use

oven gloves or a cloth when removing

the lid or handling hot containers as hot

steam will escape.

• To protect against fire, electric shock and

personal injury do not immerse cord,

plugs, or appliance in water or other

liquid.

• Unplug from the socket when not in use,

before putting on or taking off

attachments, and before cleaning.

• Do not operate any appliance with a

damaged lead or plug, or after an

appliance has malfunctioned, or has

been dropped or damaged in any way.

Contact Morphy Richards for advice on

examination, repair or electrical or

mechanical adjustment.

• Do not switch on the cooker if the

ceramic pot is empty.

• Never cook directly in the base unit. Use

the ceramic pot.

Location

• Do not use outdoors.

• Ensure that this appliance is situated out

of reach of children.

• Do not place directly under kitchen wall

cupboards when in use as it produces

large amounts of steam. Avoid reaching

over the slow cooker when in use.

Mains lead

• The mains lead should reach from the

socket to the base unit without straining

the connections.

• Do not let the cord hang over the edge of

the table or counter and keep it away

About slow cooking

• Slow cooking has always been the best

way to prepare nutritious hot meal with

minimum preparation and maximum free

time away from the kitchen. Morphy

Richards has brought this style of cooking

right up to date with this modern, cooking

system.

• Traditionally slow cooking has centred on

soups and casseroles but with this oval

ceramic cook pot you can also produce

most modern family meals and dinner

party dishes. This pot is convenient as

well as looking good enough to take

straight to the table for serving. (Always

place crock pot on a heat proof mat or

surface).

• This method of cooking is ideal for

preparing tougher cuts of meat, giving

them the long, gentle simmering that

ensures that they become tender and full

of flavour.

IMPORTANT

The slow cooker works by building up

heat and maintaining an even temperature.

To get the best cooking results, do not

remove the lid during cooking, since this will

lose heat and therefore slow down the

cooking time. The glass lid allows you to

monitor the cooking progress without

interrupting the cooking time. Each time you

remove the lid allow 10 minutes extra

cooking time.

Suitable foods

• Most foods are suited to slow cooking

methods, however there are a few

guidelines that need to be followed.

• Make sure all frozen ingredients are well

thawed out.

• Cut root vegetables into small, even

pieces, as they take longer to cook than

meat. They should be gently sauted 2-3

minutes before slow cooking. Ensure that

root vegetables are always placed at the

bottom of the pot and all ingredients are

immersed in the cooking liquid.

• Trim all excess fat from meat before

cooking, since the slow cooking method

does not allow fat to evaporate.

• If adapting an existing recipe from

conventional cooking, you may need to

cut down on the amount of liquid used.

Liquid will not evaporate from the slow

cooker to the same extent as with

conventional cooking.

• Never leave uncooked food at room

temperature in the slow cooker.

• Do not use the slow cooker to reheat

food.

• Uncooked red beans must be soaked and

boiled for at least 10 minutes to remove

toxins before use in a slow cooker.

• Insert a meat thermometer into joints of

roasts, hams, or whole chickens to ensure

they are cooked to the desired

temperature.

digital slow cooker rev 1 20/8/03 3:57 pm Page 6

Do's and Don'ts for

crock pot

• Authentic stoneware is fired at high

temperatures therefore the crock pot may

have minor surface blemishes, the glass

lid may rock slightly due to these

imperfections. Low heat cooking does not

produce steam so there will be little heat

loss. Due to normal wear and tear

through the products life, the outer

surface may start appearing 'crazed'.

• Do not put the crock pot or glass lid in an

oven, freezer, microwave or on a

gas/electrical hob.

• Do not pre-heat before adding

ingredients.

• Do not subject the crock pot to sudden

changes in temperature. Adding cold

water to a very hot pot could cause it to

crack.

• Do not allow the pot to stand in water for

a long time (You can leave water in the

pot to soak).

There is an area on the base of the crock

pot that has to remain unglazed for

manufacturing purposes. This unglazed

area is porous, therefore will soak up

water, this should be avoided.

• Do not switch the cooker on when the

crock pot is empty or out of the base.

Tips for slow

cooking

• The slow cooker must be at least half full

for best results.

• The lid is not a sealed fit. Don’t remove

unnecessarily as the built up heat will

escape. Each time you remove the lid

allow 10 minutes extra cooking time.

• If cooking soups, leave 5cm space

between the top of the cook pot and the

food surface to allow simmering.

• Many recipes require all day cooking, if

you do not have time to prepare food that

morning prepare it the night before and

store the food in a covered container in

the fridge. Transfer the food to the crock

pot and add boiling liquid / gravy.

• Most meat and vegetable recipes require

4-6 hours.

• Do not use frozen meat or poultry unless

it is thoroughly thawed out first.

• Some ingredients are not suitable for slow

cooking. Pasta, seafood, milk and cream

should be added towards the end of the

cooking time. Many things can affect how

quickly a recipe will cook, water and fat

content, initial temperature of the food

and the size of the food.

• Pieces of food cut into small pieces will

cook quicker, a degree of 'trial and error'

will be required to fully optimize the

potential of your slow cooker.

• Vegetables usually take longer to cook

than meat, so try and arrange vegetables

in the lower half of the pot.

• All food should be covered with a liquid,

gravy or sauce. In a separate pan or jug

prepare your liquid, gravy or sauce and

completely cover the food in the crock

pot.

• Pre-brown meat and onions in a pan to

seal the juices. This also reduces the fat

content if separated before adding to the

crock pot. This is not necessary if the time

is limited, but improves the flavour.

• When cooking joints of meat, ham,

poultry etc the size and shape of the joint

is important. Try to keep the joint in the

lower 2/3of the pot and fully cover with

water. If necessary cut in two pieces. Joint

weight should be kept within the

maximum limit.

IMPORTANT

When buying a joint of meat, make sure

that it will fit into the crock pot so that when it

is covered with liquid it will still be 2.5cm

below the rim of the pot. The joint must not

stick out above the rim and there should be

enough room to cover the meat with water.

The shape of the meat is just as important as

the weight.
