Microwave Porridge To Go Bowl 5 "its a brilliant way to reheat food in the microwave." Sam Warner 07 January 2021 used for reheating food at home and work. I don't understand why it's been called 'porridge' - we use it for everything as it's the perfect size for reheating leftovers for lunch. this has become our most used tupperware. There's a little flap in the lid you can pop open to release steam. you can hold it steaming hot out of the microwave without getting hurt. the handle is comfortable. it's efficient at heating food. we don't bother with the spoon. its a brilliant way to reheat food in the microwave.
