My Grandmother said "drippings" as mentioned here although she was third generation in USA. My Mother said "drippings" only when she meant the residue that would be used for another cooking procedure. I say "drippings" for the bits left in the pan when I'm making gravy for turkey. So perhaps it's a generational difference as well as Mother County - Colonies thing?
As to rarebit I make mine in a double boiler to prevent scorching.
When a child, I heard rabbit for rarebit! I was appalled anyone would eat a lovely soft cuddly rabbit. I wondered if perhaps Welsh rabbits were not as darling as American rabbits and easier to justify killing. The thoughts that run through a child's mind often remind me of a routine by Robin Williams.
Now, as to quail on toast... wow
