Method for delivering liquid heated to a desired temperature under pressure in a microwave oven

A method for brewing a beverage in a microwave oven, the method comprising:

• obtaining a device having (a) a first chamber adapted to receive and hold a first volume of a liquid, (b) a second chamber adapted to receive and hold a second volume of the liquid, (c) a vapor flow path from the first chamber to the second chamber, (d) a chamber adapted to receive and hold a cartridge containing an infusible material, and (e) a liquid/vapor flow path from the second chamber to the infusible material chamber, the liquid/vapor flow path having a liquid insertion nozzle at its distal end, wherein the first chamber is configured such that the liquid in the first chamber receives a first amount of microwave energy produced by a microwave oven during a period of time, wherein the second chamber is configured such that the liquid in the second chamber receives a second amount of microwave energy produced by a microwave oven during the period of time, and wherein a ratio of the second amount of microwave energy to a mass of the second volume of liquid is less than a ratio of the first amount of microwave energy to a mass of the first volume of liquid;
• inserting the first volume of the liquid into the first chamber and the second volume of the liquid into the second chamber;
• inserting the cartridge into the infusible material chamber;
• placing the device on top of a receiving vessel;
• placing the device and the receiving vessel into the microwave oven;
• and
• activating the microwave oven until the liquid in the first chamber reaches its boiling point and at least partially turns into a gas;
• wherein at least a portion of the gas flows through the vapor flow path from the first chamber into the second chamber thereby increasing a pressure in the second chamber;
• wherein the increased pressure in the second chamber forces at least a portion of the liquid in the second chamber through the liquid/vapor flow path and the liquid insertion nozzle and into the cartridge;
• and
• wherein the liquid delivered into the cartridge flows through the infusible material and out of the cartridge as a brewed beverage.
