Abstract

A marshmallow toasting apparatus and method caramelizes the outer skin of marshmallow and is designed for countertop use. The apparatus comprises a housing, a spit or skewer, and a heat source. The housing includes top and front walls having a common slot extending therebetween. The common slot defines a marshmallow-receiving cavity and a spit-receiving plane. The spit or skewer may be rotated by way of a rotisserie assembly, as an optional feature. The spit is receivable in the spit-receiving plane and is rotatable therein substantially parallel to the top wall. The heat source is positioned adjacent the cavity for caramelizing the outer skin of marshmallow via directed heat energy. The cavity is sized and shaped for enabling structurally free thermal expansion of marshmallow during application of heat to the cavity.

Claims

1. A marshmallow toasting apparatus for caramelizing the outer skin of marshmallow, said apparatus comprising:

a housing, the housing including a top wall and a front wall, the top and front walls having a common slot extending therebetween, the common slot defining a marshmallow-receiving cavity and a member-receiving plane;

a rotisserie assembly, the rotisserie assembly comprising a marshmallow-skewering member and means for rotating the member about its axis, the member being receivable in the member-receiving plane and being rotatable therein substantially parallel to the top wall; and

heat sourcing means for caramelizing the outer skin of marshmallow, said means being mounted within the housing adjacent the cavity for sourcing heat to the cavity.

2. The marshmallow toasting apparatus of claim 1 wherein the cavity is sized and shaped for enabling structurally free thermal expansion of marshmallow during application of heat to the cavity.

3. The marshmallow toasting apparatus of claim 2 wherein the cavity has a lateral cavity width and the common slot at the front wall has a lateral slot width, the cavity width being greater in magnitude than the slot width for accommodating marshmallow expansion during application of heat to the cavity.

4. The marshmallow toasting apparatus of claim 1 wherein the housing comprises a back wall, the common slot extending intermediate the top, front and back walls.

5. The marshmallow toasting apparatus of claim 4 wherein the common slot at the front and back walls comprises means for rotatably supporting the member during rotation about its axis.

6. The marshmallow toasting apparatus of claim 1 comprising timing means for automatically timing the heat sourcing means, said timing means operating to automatically apply heat to the cavity for select time periods.

7. The marshmallow toasting apparatus of claim 1 wherein the cavity comprises means for reflecting heat energy therewithin, said means for enhancing heat uniformity within the cavity.

8. A marshmallow toasting apparatus for caramelizing the outer skin of marshmallow, said apparatus comprising:

a housing, the housing including a top wall and a front wall, the top and front walls having a common slot extending therebetween, the common slot defining a marshmallow-receiving cavity and a member-receiving plane;

a skewer member, the member being receivable in the member-receiving plane and being rotatable therein; and

heat sourcing means for caramelizing the outer skin of marshmallow, said means being mounted within the housing adjacent the cavity for sourcing heat to the cavity.

9. The marshmallow toasting apparatus of claim 8 comprising automatic means for rotating the member about its axis.

10. The marshmallow toasting apparatus of claim 8 wherein the cavity is sized and shaped for enabling structurally free thermal expansion of marshmallow during application of heat to the cavity.

11. The marshmallow toasting apparatus of claim 8 wherein the cavity has a lateral cavity width and the common slot at the front wall has a lateral slot width, the cavity width being greater in magnitude than the slot width for accommodating marshmallow expansion during application of heat to the cavity.

12. The marshmallow toasting apparatus of claim 8 wherein the common slot at the front and wall comprises means for rotatably supporting the spit during rotation about its axis.

13. The marshmallow toasting apparatus of claim 8 wherein the housing comprises a back wall, the common slot extending intermediate the top, front and back walls.

14. The marshmallow toasting apparatus of claim 8 comprising timing means for automatically timing the heat sourcing means, said timing means operating to automatically apply heat to the cavity for select time periods.

15. The marshmallow toasting apparatus of claim 8 wherein the cavity comprises means for reflecting heat energy therewithin, said means for enhancing heat uniformity within the cavity.

16. A marshmallow toasting apparatus for caramelizing the outer skin of marshmallow, said apparatus comprising:

a housing, the housing having a peripheral wall defining a centralized heat chamber, opposed portions of said wall comprising skewer-elevating means for elevating a skewer member in superior adjacency to the heat chamber;

a skewer member, the skewer member being cooperable with said skewer elevating means for elevating a skewered marshmallow in superior adjacency to the heat chamber; and

heat sourcing means for caramelizing the outer skin of marshmallow, said means being mounted within the housing adjacent the heat chamber for sourcing heat to the heat chamber.

17. A marshmallow toasting method for caramelizing the outer skin of marshmallow, said method comprising the steps of:

skewering a marshmallow with a spit;

slot-receiving the spit-skewered marshmallow, thereby positioning the marshmallow within peripheral marshmallow expansion chamber walls;

directing heat energy toward the marshmallow from a select marshmallow expansion chamber wall;

thermally expanding the marshmallow toward the peripheral marshmallow expansion chamber walls; and

caramelizing an outer skin of the marshmallow via the directed heat energy.

18. The marshmallow toasting method of claim 17 comprising the step of rotating the marshmallow after slot-receiving the spit-skewered marshmallow.

19. The marshmallow toasting method of claim 18 wherein the marshmallow rotation is at a constant rotational speed, thereby periodically exposing the marshmallow to direct heat energy from the select chamber wall.

20. The marshmallow toasting method of claim 17 wherein the step of slot-receiving the spit-skewered marshmallow closes a heat supply timing circuit, heat energy being directed from the select chamber wall until the timing circuit opens.

21. The marshmallow toasting method of claim 17 comprising the step of reflecting heat energy from the marshmallow expansion chamber walls toward the marshmallow.

22. A marshmallow toasting method for caramelizing the outer skin of marshmallow, said method comprising the steps of:

skewering a marshmallow with a marshmallow rotisserie;

slot-receiving the rotisserie-skewered marshmallow, thereby positioning the marshmallow within peripheral marshmallow expansion chamber walls;

simultaneously directing heat energy toward the marshmallow from a select marshmallow expansion chamber wall and rotating the marshmallow via the marshmallow rotisserie;

thermally expanding the marshmallow toward the peripheral marshmallow expansion chamber walls; and

caramelizing an outer skin of the marshmallow via the directed heat energy.

23. The marshmallow toasting method of claim 22 wherein the marshmallow rotation is at a constant rotational speed, thereby periodically exposing the marshmallow to direct heat energy from the select chamber wall.

24. The marshmallow toasting method of claim 22 wherein the step of slot-receiving the spit-skewered marshmallow closes a heat supply timing circuit, heat energy being directed from the select chamber wall until the timing circuit opens.

25. The marshmallow toasting method of claim 22 comprising the step of reflecting heat energy from the marshmallow expansion chamber walls toward the marshmallow.
