What culinary delight did I re-invent? (meat and bread)

Almost, but not quite, entirely unlike [del]tea[/del] Yorkshire pudding. :smiley:

Grease bread, mmmmmmmmmmmm! :o

Sounds a bit like a bread trencher, except not used as a serving dish. Actually, that sounds like a great way to serve your meatloaf now!

So, does that mean biscuits and gravy is a medieval dish in fact, instead of a southern one?

The basic idea is ancient (far older than medieval), but Southern Americans refined and perfected it.

Naah, quick breadslike biscuits are a distinctly recent innovation.
