Operation Manual

STANDING TIME
Dense  foods  e.g.  meat,  jacket  potatoes  and cakes, 
require standing time(inside or outside of the oven) after 
cooking, to allow  heat  to  finish conducting to  cook  the 
center completely. Wrap meat joints and jacket potatoes 
in aluminium foil while standing. Meat joints need approx. 
10-15 minutes, jacket  potatoes  5 minutes.  Other foods 
such  as    plated meal, vegetables,  fish  etc  require 2-5 
minutes  standing. After defrosting food,  standing time 
should  also  be  allowed.  If  food  is  not  cooked  after 
standing time, return to the oven and cook for additional 
time.
MOISTURE CONTENT
Many  fresh foods  e.g.  vegetables  and fruit, vary in their 
moisture  content throughout  the  season,  particularly 
jacket potatoes. For this reason cooking times may have 
to be adjusted.  Dry  ingredients e.g.  rice, pasta,  can dry 
out during storage so cooking times may differ.
DENSITY
Porous  airy foods  heat more  quickly  than  dense  heavy 
foods.
CLING FILM
Cling film helps  keep the food  moist  and the trapped 
steam  assists  in  speeding  up  cooking  times.  Pierce 
before cooking to allow excess steam to escape. Always 
take  care  when  removing cling  film from  a  dish  as  the 
build-up of steam will be very hot.
SHAPE
Even  shapes  cook  evenly.  Food  cooks  better  by 
microwave when in a round container rather than square.
SPACING
Foods  cook  more quickly and evenly if  spaced apart. 
NEVER pile foods on top of each other.
STARTING TEMPERATURE
The colder the food, the longer it takes to heat up. Food 
from a fridge takes  longer  to  reheat  than food at room 
temperature.
LIQUIDS
All  liquids  must  be stirred before and during heating. 
Water  especially  must be  stirred  before  and  during 
heating, to avoid eruption. Do not heat  liquids that have 
previously been boiled. DO NOT OVERHEAT.
TURNING & STIRRING
Some  foods require  stirring during cooking.  Meat  and 
poultry should be turned after half the cooking time.
ARRANGING
Individual foods e.g. chicken portions or chops, should be 
placed on a dish so that the thicker parts are towards the 
outside.
QUANTITY
Small  quantities  cook faster than large  quantities,  also 
small meals will reheat more quickly than large portions.
PIERCING
The skin or membrane on some foods will cause steam 
to build up during cooking. These foods must be pierced 
or a strip of skin should be peeled off before cooking to 
allow  the  steam  to  escape.  Eggs,  potatoes,  apples, 
sausages etc, will all need to be pierced before cooking. 
DO NOT ATTEMPT TO BOIL EGGS IN THEIR SHELLS.
COVERING
Cover foods with microwave cling lm or a lid. Cover sh, 
vegetables,  casseroles,  soups.  Do  not  cover  cakes, 
sauces, jacket potatoes or pastry items.
