3.3OnceCookingHasFinished
Do NOT attempt to open your pressure cooker
until it has cooled and the pressure has been
released.
3.3.1 Natural Cooling – The Preferred
Method
Using oven gloves and gripping the handles,
carefully move the pressure cooker on to a
level, heat-resistant surface and leave it to
stand until the pressure has reduced and the
safety valve has lowered.
3.3.2 Rapid Cooling
If it is necessary to cool the pressure cooker
more rapidly, place it in a sink and run cold
water over it until the safety valve has lowered
DO NOT allow water to enter the pressure
cooker through the safety valve or through the
pressure regulator.
3.3.3 Opening The Pressure Cooker
Once the safety valve has lowered, the pressure
limiting valve can be removed. When all of the
steam has escaped and the valve rod has been
released, the lid can be opened. If the indicating
valve rod has not dropped, it means that there
is still some pressure in the pressure cooker.
To ensure your safety, the cover cannot be
opened until the indicating valve rod has
dropped. DO NOT force the pressure cooker
open.
Under these circumstances, the indicating valve
may be pressed down, using a needle or a
cocktail stick to enable the remaining steam to
escape.
The pressure limiting valve should always be
removed before opening the cover.
Use oven gloves to open the cover to avoid the
risk of injury.
If soft foods, such as rice, are being cooked,
shake the pressure cooker gently to relieve the
pressure before opening. Similarly with foods
such as soup, shake gently to disperse any
bubbles as they could burst and spray hot
liquid, causing injury.
Next, press down the lock button on the top of
the cover to unlock the lid.
3.4HowtoUsetheSteamer
Some recipes, such as Christmas pudding,
require pre-steaming before being brought to
cooking temperature. Pre-steaming can be
carried out in a closed pressure cooker, over a
medium heat.
Once steaming begins, the heat should be
turned down as low as possible in order to
reduce the amount of steam that escapes and
the amount of water that is consumed. Once
pre-steaming is complete, check that there is
still sufcient water remaining to complete the
cooking stage.
The cover should be locked into position and
the heat turned up to bring the pressure cooker
up to cooking pressure.
The basket is used to prevent the food from
coming into contact with the liquid while, at the
same time, allowing the steam to circulate freely
in and around the food.
The basket may be lined with aluminium foil
when cooking foods such as rice or pasta.
However, in order to prevent the rice or pasta
from blocking the safety vents, the basket
should be covered with greaseproof paper,
which must be tied down securely around the
sides of the basket.
