#1 Does this do potato waffles? Are the plates ceramic?
It can cook all kinds of waffle. Even cooks an egg or omelette. Just spray with some kind of oil spray. Yes they are ceramic plates and they clean up very easily - one at a time in soapy water (not D/W), then leave on kitchen towel to air dry. A fantastic way to cook keto waffles too.
#2 Is the product dimension mentiond correct? 9.3D X 10.9W X 3.7 centimeters sound minuscule. Is it in Inches probably?
Yes that's inches and it makes 2 x 4.5inches x 4inches waffles
I don't think you need any if you are careful to use plastic utensilsvto remove waffles and when washing them in the sink. I have used my waffle maker most days for over 6 months and the plates are like new
