How Does it Work?
PREPARING TO COOK
NOTE:
• Thoroughly wash the inner pot
before each use.
• The minimum amount of
ingredients needed to cook in the
pressure cooker is ⅕ of the capacity
of the inner pot.
• The minimum amount of liquid
needed for cooking is 4 cups/1500
mL. (This may vary depending on
the recipe you are following.)
3. Add ingredients to the inner
pot. Ingredients and water/
liquid should not exceed ⅔ of
the inner pot capacity. When
cooking dry ingredients such as
rice or beans, do not ll the past
½ the capacity of the inner pot.
NOTE:
• Overlling may risk clogging
the pressure release valve and
developing excess pressure, which
may cause leakage, personal injury,
or damage to the device.
• Do not ll pass the MAX line for non-
pressurized cooking programs.
1. To open the lid, turn the latch
counterclockwise so that the
“Open” mark aligns with the
(arrow symbol) then pull up on
the lid handle.
2. Check all parts on the lid to make
sure they are properly assembled.
Make sure there is no debris blocking
the oat and anti-clog lter, and that
they are able to easily move up and
down. Check the sealing ring to see
if it is properly positioned along the
rack.
14
4. Wipe away any excess moisture
or debris from the exterior of
the inner pot, then place it into
the housing. Slightly rotate
the inner pot to ensure good
contact between the pot and
the heating element.
5. Close the lid, then turn the latch
clockwise so that the “Close”
mark is aligned with the (arrow
symbol) on the housing.
6. Set the pressure release valve
to the “Sealed” position.
NOTE:
• It is perfectly normal for the
pressure release valve to be loose.
The valve works by weight and
simply rests on top of the release
outlet. It can be removed for
cleaning by pulling it straight out.
7. Make sure water collection cup
is properly attached onto the
pressure cooker.
8. Plug the pressure cooker into a
powered electrical outlet. The unit
will beep and the display will show
“--:--”, indicating that the unit is in
standby mode.

NOTE:
• It may take anywhere from 5 to 35
minutes to pressurize depending on
the amount of food in the inner pot.
The more food inside the pot, the
longer it will take to reach optimal
pressure.
• CAUTION: While the cooker is
pressurizing, it may automatically
release excess pressure through
the pressure release valve. This is
a built-in safety feature to ensure
the pressure cooker is maintaining
a safe pressure level for proper
operation. This may also happen if
there is less than 4 cups of liquid in
the inner pot.
6. Once the unit reaches optimal
cooking pressure, the unit will beep
once and the display will begin to
countdown.
7. The pressure cooker will beep three
times to alert you when cooking has

sweet and healthy snack.
NOTE:
If your yogurt is too thin, run it through
a strainer before serving.
Jiu Niang
Jiu Niang, also known as fermented
glutinous rice, is a sweet and mildly
alcoholic delicacy of Asia. Glutinous
rice, more commonly known as sticky
rice, is used in making Jiu Niang and
contains a high concentration of starch
that is converted to sugar during the
fermentation process.
NOTE:
Make sure that all tools and utensils are
clean and free from bacteria, oil and
salt before you start cooking.
1. Soak two cups of glutinous rice in
cold water for at least 5 hours until
the rice grains become easily broken
with ngers. Meanwhile, prepare 1
cup of boiling water and set aside so
that it completely cools down.
2. Drain the water and wrap the soaked
rice with cheesecloth. Place it into
a steaming basket, and place the
cheesecloth on steamer rack and
add 2 cups of water into the inner
pot. Cook the rice using the ‘Steam Vegetable’ function for 30 minutes.
Allow the the pressure to naturally
release before opening the lid (See
Safely Removing the Lid).
3. Place starter yeast powder in a glass
or ceramic container, and set the
container to the side.
4. Allow the steamed rice to cool down
below 95°F/35°C. Mix the cold boiled
water and yeast powder with the rice
thoroughly in the container. Make
sure that each rice grain is separated,
rather than stuck together. Gently
press the rice mixture together and
leave a hole in the middle of the
mixture.
5. Add water to the 3 cup mark in the
inner pot. Place the container into
the inner pot with the steamer
rack. Water should submerge to
24
about 0.5in/1cm of the bottom
of the containers for even heat
conduction. Make sure to close the
lid of the containers to avoid excess
evaporation from the rice.
1. Make sure the unit is connected to a
powered electrical outlet.
6. Press the ‘Yogurt’ button and then
press the ‘Adjust’ button twice
for “Less” to access the Jiu Niang
function (the display will read “JIUN”).
The default fermentation time is
24 hours. You may need to change
the time based on the type of yeast
used; use the ‘Cook Time’ button
and the ‘+’ and ‘-’ buttons to change
the cooking time.
7. Jiu Niang will be ready when the
program nishes. A well-made
fermented glutinous rice has
transparent liquid and some small
gas bubbles with an aroma of
liquor and is very sweet. If there are
some white fungi on the surface,
this is normal. If it has black fungi,
the rice was contaminated during
the process and it should not be
consumed. Avoid running the
fermentation for too long, which
causes the rice to turn sour.
8. When the program is nished, the
pressure cooker will beep three times
and go into standby mode.
Manual Pressure Cooking Mode
Your new Cosori Electric Pressure Cooker
also gives you the option to manually
set up the pressure cooker for complete
control over your cooking settings. There
are two methods for setting up the
manual pressure cooking mode. Please
note that the ‘Adjust’ function will not
work with this setting.
Method 1: Pressure Level
NOTE:

2. Press the ‘Manual’ button once
to select the manual pressure
level cooking function. The
pressure level indicator will
be illuminated, indicating that
the pressure cooker is set to
manual pressure level mode.
3. Press ‘Pressure/Temp’ and use
the ‘+’ or ‘-’ buttons to adjust
the pressure level.
4. Press the ‘Cook Time’ button,
then use the ‘+’ or ‘-’ buttons to
select your cooking time.
5. Press ‘On/Start’ to begin
cooking. The display will show
the image below, indicating that
the unit is pressurizing.
25
6. Once the unit reaches optimal
cooking pressure, the display
will begin to count down.
7. The pressure cooker will beep three
times when cooking has nished, and
it will automatically set itself to the
Keep Warm mode for 6 hours. (See
Safely Removing the Lid)
Method 2: Temperature

powered electrical outlet.
2. Press the ‘Manual’ button
twice to set the unit to manual
pressure temperature mode.
4. Press the ‘Cook Time’ button,
then use the ‘+’ or ‘-’ buttons to
select your cooking time.
NOTE:
When the programmed temperature
exceeds 248°F/120°C, the maximum
time that can be set is 30 minutes.
5. Press ‘On/Start’ to begin
cooking. The display will show
the image above, indicating
that the unit is pressurizing or
heating.
3. Press ‘Pressure/Temp’ and use
the ‘+’ or ‘-’ buttons to adjust

Safely Removing
the Lid
• For your safety, open the lid slowly.
Escaping steam is hot and may
cause burns to exposed skin.
• Do not open the lid before all
pressure has escaped through the
exhaust valve and the oat valve has
completely fallen back into the lid.
• The handle may also be hot when
cooking has nished. The following
methods should be used when
opening the lid:
QUICK RELEASE
1. Unplug the pressure cooker to
turn it o. Use oven mitts or pot
holders to switch the pressure
release valve from “Seal” to
“Release.”
NATURAL RELEASE
When using the natural release method,
please adhere to the following cautions:
• DO NOT open the lid until the pressure
inside the pot has been completely
released. For your safety, the lid will
remain locked until the oat valve
drops down.
• If the oat valve is stuck due to food
debris, the push it down with a pen or
chopstick. Make sure all of the pressure
has been released beforehand through
the pressure release valve.
• To avoid injury, never attempt to force
the oat valve down in order to open
the lid. DO NOT open the lid until all of
the pressure has been released.
• It is recommended to use the natural
release method when cooking liquids
such as soups or rice porridge.
Immediately releasing pressure after
cooking such foods may result in food
spraying out through pressure release
valve.
1. Once cooking is complete, turn
o the pressure cooker’s power
by unplugging the power cable.
2. Wait until all pressure has
released and oat valve has
dropped down to open the lid.
3. For your safety, open the lid slowly
and away from your face. Escaping
steam will be hot.
15-20 minutes
2. Let the unit cool down on its
own for 15-20 minutes or until
the oat valve drops down
before opening the lid.
27
NOTE:
To help speed up cooling, place a wet
towel on the metal part of the lid. Make
sure not to cover the pressure release
valve.
3. Set the pressure release valve
to the “Release” position to let
out any remaining pressure in
the unit.
4. Wait until oat valve drops
down to open the pressure
cooker.
5. Unlock the lid by turning it
counterclockwise, then carefully
lift the lid away from your face.
The steam coming out from the
pressure cooker will be hot.
28
Additional Tips for Pressure Cooking
• Use extreme caution when moving the pressure release valve to the “Release”
position. Keep your hands and face away from the valve openings, failure to do so may
result in serious injury.
• DO NOT attempt to open the lid until the pressure inside the unit has completely
been released. Wait until the oat valve drops down before opening. Do not attempt
to force the lid open while the oat valve is still up.
• When opening the lid, the inner pot by stick to the lid. This is due to a vacuum created
by cooling. Make sure to release any remaining pressure through the pressure release
valve.
• If the oat valve is stuck, it may be that there is still pressure inside of the pot. Once
all of the steam has been released, use a pen or a long, thin utensil to push the oat
valve down.
• The time it takes for the cooker to pressurize and cook food varies due to the amount
of food in the inner pot and the temperature of ingredients. Cold food will take longer
to cook than food at room temperature. It is not recommended to cook raw frozen
foods such as meat and sh in the Cosori pressure cooker.
• Recommended rice cooking ratios:
* White & brown rice: 1 cup of dry rice to 1.5 cups of water
* Jasmine rice: 1 cup of dry rice to 1 cup of water
