In a solar cooker of the box- or panel-type, it is prepared in a different way: you just put the corn flour into the cold water (1.5 parts water, 1 part cornmeal), stir well, and then put the covered pot into the cooker. There may be no stirring necessary since the heat is very even and there is no concentrated heat coming from a flame under the pot. Another advantage of this method is that the pot almost never needs any cleaning afterwards.
