Will it be okay to just skip the covering?
Place a piece of aluminum foil over the top of the panRun your fingers around the edge of the pan to form a tight sealWould be best if the foil was doubled to make it thickerYou could also try placing another pan on top of the one you are cooking the rice inWeight the top pan down so there will be no gapsIf you do this you might want to put a kitchen towel between the two to seal off any gaps.
