- Trial Run before Cooking
Trial Run before Cooking
Even if you have used a pressure cooker previously, take a trial run before cooking
in your kitchen. This section will take you step-by-step through your trial run
in about 30 minutes.
1. Preliminary Steps
Remove label and wash cooker, removing any adhesive with baby or vegetable oil.
Read The benefits of Pressure cooking, Important Safeguards, Parts of a United Pressure
Cooker and Basic Product Information. Identify parts. Remove and place the pressure
regulator on the steam vent, the sealing ring on the lid curl. Close and open the
pressure cooker a few times.
2. Placing Cooker on
Pour 2 cups water in cooker body. Add 1 teaspoon (5 ml) lemon juice or vinegar (not
for anodised cookers) to prevent discolouring the cooker. Remove pressure regulator
from steam vent. Look through steam vent and ensure it is clear.
Check and adjust the seating of the sealing ring on the lid curl by patting down
snugly. Close cooker. Place cooker on high heat.
3. Ensuring a Steam-tight
Seal When water boils, hot air and/or steam should issue only from the steam vent.
If steam comes out around the edge of the lid, check the centralization of the lid
thus: unlatch and reposition the lid by moving the lid slightly towards the spot
where steam is escaping and relatch. DO NOT TOUCH LID with bare hands since it will
4. Placing the Pressure
The pressure regulator automatically maintains the cooking pressure of about 15
pounds per square inch (1 kg per square cm). The pressure regulator has to be placed
on the steam vent and pressed into position. When the pressure regulator is pressed
down on the steam vent, there is a slight click which indicates the pressure regulator
is in the correct position.
THE UNITED COOKER WHISTLES
AT FULL OPERATING PRESSURE
5. How to Recognize Full
After the pressure regulator is placed on the steam vent, there is at first a very
low hissing sound of steam from the pressure regulator. Then steam emission increases
to full force and the pressure regulator lifts with a whistling sound. The cooker
is now at full operating pressure. This is the point at which to reduce heat and
start timing the recipe.
6. Maintaining Pressure
on Reduced Heat
Once full pressure is reached, reduce heat from HIGH to MEDIUM or lower. The pressure
inside the cooker will be maintained at about 15 pounds per square inch (1 kg per
square cm). If the cooker whistles too frequently (more than 4 whistles per minute),
reduce the heat still further. If there is no steam coming out of the pressure regulator
for a few minutes, increase the heat gradually until the steam comes out. Please
remember that, particularly on electric heat, it may take some time for heat level
adjustments to have an effect on the frequency of whistles. A little practice will
make clear the correct heat setting and adjustments, if any, that may be required.
7. Releasing Pressure
Turn off heat. Remove pressure cooker from heat. With a fork, slightly lift pressure
regulator to release steam. Do not remove pressure regulator.
8. Final Steps
Open cooker. Empty out water. Wash and wipe dry body, lid and pressure regulator.
Store without closing the pressure cooker. Before cooking in your Pressure Cooker,
