‘S’ (Slow) cooking
(Main oven)
The ‘S’ setting is a low temperature
setting.
You can cook on ‘S’ throughout, or use a 30
minute ‘boost’ period at gas mark 6 and then ‘S’
cook.
When roasting joints, poultry or pot
roasting, always cook at Mark 6 for 30
minutes at the beginning of the cooking
period.
You can ‘S’ cook for periods of 6 to 12 hours.
This technique is particularly useful if you want to
cook a dish overnight or while you are out at
work during the day.
Frozen foods must be thoroughly thawed
out before ‘S’ cooking.
Whole poultry should not be cooked on ‘S’.
Chicken casseroles are fine.
Casseroles must be brought to boiling
point on the hotplate immediately before
‘S’ cooking.
Poultry and rolled joints should not be stuffed
before cooking. The stuffing should be cooked
separately. Poultry and pork should be cooked in
the top half of the oven, and other meats not
lower than shelf position 4.
A roasting joint should be covered with
cooking foil, or with a roasting bag to
reduce shrinkage and retain juices.
Should further browning be necessary, uncover
the meat and increase the temperature to Mark 4
for a short period.
Cut root vegetables into small pieces
unless cooking whole, e.g. jacket
potatoes.
Cover dishes tightly with a lid or foil to prevent
evaporation and transfer of flavour.
Once the oven has been loaded and the
‘S” setting is in operation resist the
temptation to open the oven door. Heat
will be lost and the cooking time
extended.
A meat thermometer is recommended for
checking that a joint or poultry is sufficiently
cooked. Insert the probe through the thickest
part of the meat. The temperatures to be
expected are as follows.-
Beef
rare
60°C/ 140°F
medium
71°C/ 160°F
well done
77°C/ 170°F
Lamb
82°C/ 180°F
Pork
fresh
88°C/ 190°F
cured
77°C/ 170°F
Poultry
90°C/ 195°F
Veal
77°C/ 170°F
Cooking using the timer
The timer can be used to turn just one oven or
both on and off automatically. The start and stop
time must be the same for both ovens but
different cooking temperatures can be set.
If you want to turn one of the ovens on at
the same time as the timer is set for
automatic cooking, you must wait until
the timer has turned on the oven/ ovens
first. Then you can adjust either of them
manually in the normal way.
You can set the oven to turn on any time over
the following 24 hour period.
If you want to cook more than one dish,
choose dishes which require
approximately the same time. However,
dishes can be ‘slowed down’ slightly by
using small containers and covering
them with aluminium foil, or ‘speeded up’
slightly by cooking smaller quantities or
placing in larger containers.
Very perishable foods such as pork or fish
should be avoided if a long delay period is
planned, especially in hot weather.
Don’t place warm food in the oven.
Don’t use an oven already warm.
Don’t use if an adjoining oven is warm.
Avoid using wine or beer if there is a delay
period, as fermentation may take place.
To avoid curdling, cream should be
added to dishes just before serving.
Fresh vegetables which may discolour during a
delay period should be coated in melted fat or
immersed in a water and lemon juice solution.
Fruit pies, custard tarts or similar wet mixtures on
top of uncooked pastry are only satisfactory if
there is a short delay period. Dishes containing
leftover cooked meat or poultry should not be
cooked automatically if there is a delay period.
Whole poultry must be thoroughly
defrosted before placing in the oven.
Check that meat and poultry are fully
cooked before serving.
