Microwavable construct with contoured heating surface

A tray for heating, browning, and/or crisping a food item in a microwave oven, the tray including a first centerline extending in a first direction and a second centerline extending in a second direction, wherein the first centerline is substantially perpendicular to the second centerline, the tray comprising:

• a substantially planar base;
• a platform extending upwardly from the base, the platform including
• a heating surface having a first height relative to the base so that the heating surface is positioned above the base, wherein the heating surface comprises microwave energy interactive material, and
• a plurality of faces that extend outwardly and downwardly from the heating surface towards the base;
• and
• at least one upwardly open channel extending at least partially across the platform, the channel including a lowermost portion having a second height relative to the base so that the lowermost portion of the channel is positioned above the base, wherein the second height is less than the first height, such that the lowermost portion of the channel is positioned between the base and the heating surface.

A tray for heating, browning, and/or crisping a food item in a microwave oven, the tray including a first centerline extending in a first direction and a second centerline extending in a second direction, wherein the first centerline is substantially perpendicular to the second centerline, the tray comprising:

• a substantially planar base;
• a first heating surface in an elevated position relative to the base;
• a second heating surface in an elevated position relative to the base;
• a microwave energy interactive material overlying at least a portion of each of the first heating surface and the second heating surface;
• a first venting channel extending at least partially across the first heating surface;
• and
• a second venting channel extending at least partially across the second heating surface, the first venting channel and the second channel each being upwardly open,
• wherein
• the first heating surface and the second heating surface are each substantially uniform in height in the first direction along the first centerline, and
• the first heating surface and the second heating surface each decrease in height in the second direction from the first centerline outwardly towards the base.

A tray for heating, browning, and/or crisping a food item in a microwave oven comprising:

• a substantially planar base defining a peripheral margin of the tray;
• and
• a substantially circular platform extending upwardly from the base, the platform including an uppermost surface for supporting a food item, wherein the uppermost surface of the platform has a height relative to the base, and wherein the height of the uppermost surface decreases substantially uniformly from a center of the platform towards the base, so that the uppermost surface of the platform has a substantially domed shape,
• wherein the platform includes a plurality of microwave energy interactive areas and a plurality of microwave energy transparent areas.
