Yep, you have to grate the potatoes right before you're ready to make them. I heat my oil when grating the potatoes. Also keep the juice squeezed out that will gather in the bottom of the bowl...For Christmas I am experimenting by putting grated walnuts into the sweet potatoe batter and a smidgen of coconut with the brown sugar...My pleasure Eagle!!
