Abstract

A microwave-reflective vessel with a cold-keeping agent is chilled in a freezer. Then a frozen foodstuff, contained in the chilled vessel, is deep heated by microwave energy while the foodstuff'"'"'s surface is cooled by conventional heat loss to the chilled vessel. The invention concerns frozen, foodstuffs a) that are difficult to penetrate with a spoon, as frozen whipped cream, b) that frozen are too rigid to easily masticate, as a frozen Milky Way®, and c) that, when cooled on the outside and warmed on the inside, provide a novel taste treat, as a cool outside, warm inside, jelly doughnut. Multiple purpose covers are disclosed that a) retard freezer burn when in a freezer, b) maintain freezing temperatures when in a microwave oven, and c) serve as chilled dessert dishes on the dining table.

Claims

1. A method for heating, in a microwave oven, a frozen foodstuff while said foodstuff is contained in a cold keeping container with a microwave-shielded cold keeping agent that includes the steps of:

selecting said container,

exposing said container to a freezing temperature for, at least, the amount of time required to chill said cold keeping agent to below the freezing temperature of said foodstuff so that said cold keeping agent will, subsequently, maintain, a freezing environment about said foodstuff when said foodstuff is in said container,

placing said foodstuff in said container, and

subsequently, exposing said foodstuff, in said cold keeping container to microwave energy.

2. The method of claim 1 that includes:

covering said container with at least one cover of microwave-transparent material where said cover can serve as a chilled serving dish.

3. A method of heating a frozen foodstuff in a microwave oven while said foodstuff is contained in a container with a cold-keeping agent that includes the steps of:

chilling a microwave-reflective, double-walled vessel that has an open top and a closed bottom and that comprises an inner cup member and an outer cup member with an annular chamber there-between substantially filled with a cold-keeping agent, to, at least, the freezing temperature of said foodstuff,

containing said frozen foodstuff in said inner cup member so that when said vessel is exposed to microwave energy, said microwave energy can defrost, at least, a portion of said frozen foodstuff, and

subsequently exposing said portion of said frozen foodstuff in said chilled vessel to microwave energy for a predetermined time.

4. The method of claim 3 that includes:

freezing said foodstuff where the nature of said foodstuff is such that, when said foodstuff is frozen, it freezes into a rigid mass,

exposing said frozen foodstuff to said microwave energy until, at least, one serving portion, of said rigidly frozen foodstuff, becomes defrosted enough to be served.

5. The method of claim 3 that includes where said frozen foodstuff is placed on a microwave transparent support member in said inner cup member so that microwave energy, entering said inner cup, is able to encompass and enter said foodstuff.

6. A method of claim 5 that includes where said foodstuff is selected from a foodstuff group of that consists of a microwave-lossy outer layer containing a microwave-lossy filling.

7. The method of claim 6 that includes where said frozen foodstuff is a chocolate covered candy.

8. The method of claim 6 that includes where said frozen foodstuff is a baked dough that has a filling.

11. The defrosted foodstuff with a cool outer layer containing a warm filling resulting from the method of claim 6.

9. A method for defrosting a serving portion of a microwave lossy frozen foodstuff that includes the steps of:

chilling a metal, double-walled vessel, that has an open top and a closed bottom and that comprises an inner vessel cup member and an outer vessel cup member with an annular chamber there-between substantially filled with a cold-keeping agent, for, at least, the amount of time required to chill said cold-keeping agent to below the freezing temperature of said frozen foodstuff so that, when said vessel is exposed to microwave energy, said cold-keeping agent will supply a below freezing temperature to areas of said foodstuff in close proximity to the metal walls of said inner member,

where said inner vessel'"'"'s open-top permits microwave energy to reach said frozen foodstuff when said frozen foodstuff is located in said vessel,

placing said frozen foodstuff into said vessel, and subsequently

when it is time to serve said frozen foodstuff, exposing said vessel, with said frozen foodstuff therein, to microwave energy for a predetermined period so that, at least, a top portion, of said frozen foodstuff, is defrosted.

10. The method of claim 9 that includes:

removing a predetermined amount of said defrosted foodstuff from said vessel, and

subsequently, letting the defrosted foodstuff, remaining in said inner vessel cup member, freeze from proximity to the cold stored within said chilled cold-keeping agent.
