My mum is absolutely obsessed with keeping food hot and is convinced that hot food being put onto cold (or even warm) plates will make the food "freezing" in the time it takes for it to be brought to the table.
This caused much angst at Christmas when there was a constant juggle of needing space in the oven/microwave for cooking, and for endless piles of serving dishes and plates to heat up. (I am kind of with her on serving dishes although I wouldn't consider a meal ruined if they weren't red hot)
Both my brother and I have on separate occasions reassured her that no-one in our respective households is bothered by hot plates so if she needs the space she could just heat her and my dad's plates and we would be fine, but to no avail.
Obviously when she eats at my house I make sure her and my dad's plates are hot as this is her preference.
So, what is it with hot plates people? As I stood at a sink of very hot water on Christmas Day dunking plates I really was wondering.
(She also has a thing about pasta going cold and shrieks from the kitchen to eat up before it freezes as I'm carrying plates through)
