Collapsible Microwave Plate Cover

The base ring is about 26.5 cm across, so it sits over plates and bowls smaller than that. On a bigger dinner plate it rests on the plate itself, around the food.

Covering food in the microwave is the job the supplier makes it for. They give no maximum temperature, so keep it out of the oven, off the grill setting and away from a hot hob.

Food gives off steam as it heats. Under a sealed cover that steam has nowhere to go, so it lifts the cover or turns crisp edges soggy. The holes in the top let it out while the plastic between them stops sauce reaching the walls.

No. Some covers sold online cling to the microwave ceiling with magnets, and this one has none. It folds to a flat disc and lives in a drawer between meals instead.

Yes. Turn it over, pull the sides open and rinse grapes, berries or salad leaves in it; the water runs out through the holes that are now underneath. Rinse it again before it goes back over a plate.

Folded, the sides collapse into the 26.5 cm base ring, so it needs a drawer at least that wide. The supplier gives no folded height, only that it folds flat.
