My dad grew up in England and my grandma would make Yorkshire pudding for Thanksgiving. I remember it being very tasty, but have never been able to find adequate substitutes to make it without using meat drippings. It won't puff up right.
So your biscuits are scones LOL

We have them with cream and jam.
Confused re Gravy = sauce ?
Use lard for yorkies but any bun tin containing very hot oil, smoking! will do the trick, really! Have a go, yum!
I don't know if I would say they are quite comparable to scones. (at least not the ones I've had at tea houses, but those might just be an Americanized version) Scones to me are a bit more crumbly, and sweeter.
Biscuits (unless they are overdone) are usually softer and fluffier, and not as inherently sweet.
As for gravy, yeah I would say sauce is fairly accurate. fairly thick consistency for a liquid, usually has a turkey/sausage flavoring base.
Usually we just cover the biscuits in it ^_^
