Random questions for the English here...

[novass]

...or anyone that can answer.

First, what is a biscuit in relation to "tea and biscuits"? I gather that a biscuit is a cookie, but is it a specific brand/type of cookie or anything?

Second, what exactly is a bacon buddy? Some type of bacon sandwich? I tried searching but all I came up with was random crap including stuffed bacon toys

Anyway, nothing too important, just a couple of mysteries to me

Thanks in advance!
