attaching a lid of the pressure cooker to the cooker body for pressurized cooking;

moving a portion of the steam regulation valve to a first position to release steam in the cooking chamber via a flow path through the steam regulation valve, the flow path having a first cross-sectional area in response to a first pressure in the cooking chamber; and

moving the portion of the steam regulation valve to a second position to release steam in the cooking chamber via the flow path through the steam regulation valve, the flow path having a second cross-sectional area in response to a second pressure in the cooking chamber,

wherein the first pressure is higher than the second pressure, and

wherein the first cross-sectional area is smaller than the second cross-sectional area.

61 . The method of claim 60 , wherein a biasing force is applied to the portion of the steam regulation valve, and wherein the portion of the steam regulation valve is biased towards the second position when the portion of the steam regulation valve is in the first position.

62 .- 133 . (canceled)

134 . A pressure cooker, comprising:

a cooker body and a lid enclosing a cooking chamber; and

a steam regulation valve,

wherein the cooker body includes cooker teeth, the lid includes lid teeth, and the cooker teeth and the lid teeth are configured to mutually latch to ensure the lid is locked onto the cooker body during cooking, and

wherein the steam regulation valve comprises:

a sleeve extending between an upper portion of the sleeve and a lower portion of the sleeve, the sleeve having an inner lumen extending between the upper portion of the sleeve and the lower portion of the sleeve; and

a telescoping housing extending through the inner lumen and including at least one opening through which a flow path passes,

wherein the telescoping housing is movable relative to the sleeve to decrease a cross-sectional area of the flow path in response to an increase in pressure applied to the telescoping housing.

135 . The pressure cooker of claim 134 , wherein the telescoping housing is movable relative to the sleeve to decrease the cross-sectional area of the flow path linearly in response to an increase in pressure applied to the telescoping housing.

136 . The pressure cooker of claim 134 , wherein the telescoping housing is movable relative to the sleeve to decrease the cross-sectional area of the flow path non-linearly in response to an increase in pressure applied to the telescoping housing.

137 . The pressure cooker of claim 134 , wherein the telescoping housing is movable relative to the sleeve to increase the cross-sectional area of the flow path in response to a decrease in pressure applied to the telescoping housing.

138 . The pressure cooker of claim 134 , wherein as the telescoping housing moves to decrease the cross-sectional area of the flow path in response to an increase in pressure applied to the telescoping housing, a constant biasing force resists the movement of the telescoping housing.

139 . The pressure cooker of claim 134 , wherein as the telescoping housing moves to decrease the cross-sectional area of the flow path in response to an increase in pressure applied to the telescoping housing, a biasing force resists the movement of the telescoping housing, and changes linearly.
