Blimey, this has caught on 
I must admit that it felt ridiculous yesterday wrt serving; MIL had heated the plates to nuclear, so I had to cross the room to the other side of the table, collect central dish of food, come back to my own plate (which was scorching and impossible to touch) and dish up for myself. DH meanwhile had to make sure kids didn't burn themselves on their insanely hot plates.
We are now home and grazing amongst room temperature snacks, Lord be praised
