An expresso coffee maker for use in a microwave oven. The water is stored in a microwave transparent reservoir or container which is adjacent to the pot. The pot and reservoir are coupled in a fixed spacial relationship by a collar. The collar includes a strainer which presses against a layer of coffee grounds when the collar is rigidly secured to the reservoir. The compressed coffee grounds in combination with the strainer form a pressure resistant seal over the opening of the reservoir. The water in the reservoir is heated by microwave energy. The pressure rises to a level sufficient to force steam and water through the coffee grounds into the pot.

The method of making espresso coffee in a microwave oven comprising the steps of: pouring a fluid into a substantially cylindrical pressurizable microwave transparent container having an open end on top surrounded and defined by a lip on the container; inserting a perforated metal basket in said container through said open end, said basket having a flange seated on said lip of said open end wherein the bottom of said basket is supported slightly above said fluid; positioning a heaping supply of coffee grounds in said basket; securely attaching a ring collar to said container, said ring collar having a perforated metal plate covering said open end and pressing downwardly on said grounds, compressing said grounds between said basket and said plate; inverting said container, metal basket, and attached ring collar, said fluid being retained in said container by the size of the perforations in the perforated metal basket and plate and said compressed grounds; heating said fluid in said inverted container with microwave energy to raise the pressure within said container wherein said fluid is forced through said perforated metal basket and plate and said grounds to make espresso coffee; collecting said espresso coffee in a metallic pot within the field of said microwave energy wherein the beverage produced is shielded from said microwave energy; and providing for the rapid escape of gases from said pot. The utensil recited in claim 15 wherein said container comprises a pressure relief valve.
