It was - SO - It wasn't.

       I recently had an attack of clever?  I did about 2 or 3X the spuds I needed. Lot one - became an ingredient for my Corned Beef Hash. Lot two - Topped a Shepherd's Pie. (More accurately, I suspect, a Cowherd's Pie); while Lot number three was scheduled to go with a Chicken Breast, some of my Brussel's Sprouts and the tale end of my Purple Broccoli which A. N. Other recently mocked on amount - there was enough for me with Spuds and sprouts.   ;¬). 
      Lot three stayed on a plate - now we'll see the title explained.  The Hen bit went into the Air Fryer wrapped in Al foil,  The two veg. shared a Pan and the Plate went into the Microwave.
       Title explanation?  -  A few days ago I thought I saw a possible crack on the plate, but wasn't sure; it's @£$%^&  ancient and the last one of an old set; I couldn't guess how many decades old.  I stole the message from the back and made it legible.  I didn't check, but wasn't bothered as it was the last one anyway, with plenty Denby© left.   -   It WAS a crack - SO - it WASN'T microwave proof.
