Is there a tea bush growing within 3,000 miles of Yorkshire?
Why would there need to be? Although they claim it was introduced in 1886, wasn't "Yorkshire Tea"'s current blend actually created during the rationing years by sweeping up crud and bagging it? Certainly tastes like it every time I've been forced to ingest some. Politeness can be challenging.
It seems that "Yorkshire Tea" (and several other British "blends") is to tea what tofurkey is to roasted fowl.
