Golden rules when pressure cooking
(for UK Consumers)
For 6 Litre models only.
• The minimum quantity of liquid required for normal cooking is 250 ml (½ pint)
for the first ¼ hour cooking. For each additional ¼ hour, or part of ¼ hour, add a
further 150 ml (¼ pint) of liquid. For example, 45 minutes cooking requires 600
ml (1 pint) of liquid. Note: This is only a general guide. Certain foods, such as
rice, pulses, steamed puddings and Christmas puddings may require extra water
(see text below).
• When steaming foods in the basket use a minimum of 750 ml (1¼ pint) water in
the cooker.
• Always use a liquid that gives off steam when boiled e.g. water stock, wine, beer,
cider. Never use oil or fat. All pressure cooking requires some liquid.
• Whatever the size of pressure cooker, the maximum filling level when all the
ingredients and liquid have been added are:
Solid foods e.g. vegetables, meat joints: no more than two-thirds full
Liquids and cereals e.g. soups, stews, rice, cereal and pasta: no more than half
full
Pulses e.g. dried beans and dried peas: no more than one-third full
• When cooking pulses they swell up and tend to froth up. Use 1.2 litres (2 pints)
water for every 450 g (1 lb) pre-soaked weight of pulses. Remember all dried peas
and dried beans, must be soaked in boiling water for 1 hour before cooking. Drain,
rinse thoroughly and cook in fresh water. Never eat uncooked beans or peas.
Soaking is not necessary for red lentils. The high temperatures achieved in the
pressure cooker ensure that any natural toxins in the pulses are destroyed.
Canned beans and pulses can simply be drained and rinsed before adding to the
pressure cooker.
• For steamed suet puddings, sponge puddings or Christmas puddings, a short pre-
steaming time is best to enable the raising agent to activate and prevent a heavy,
close texture. Extra liquid is required so use a minimum of 1½ pint/900 ml of
boiling water for a combined steaming and cooking time of up to 1 hour. For
each additional ¼ hour of cooking, or part of ¼ hour, add a further ¼ pint/150
ml of boiling water. Pre-steaming is done with the operating valve in the steam
release position on a low heat for the required time. Then turn the operating valve
to either
or , and increase the heat to bring to full pressure. Lower the
heat and pressure cook for the required time.
• Pressure operates at 50kPa (7 psi / 7lbs pressure) and pressure at
80kPa (12 psi / 12lbs pressure).
