"Gunpowder Tea" is [ or was? ] a brand of loose tea out of Assam in India, very dark in color and very strong. I suppose it got its name from the similarity with the military substance!

The kipper is a North Sea herring, which has been split down the middle and flattened out then smoked with oak or beech chips as a preservation method. Unsplit whole herring are called bloaters, [ or in France "Gendarmes" [Linked Image] -there is a passing resemblance!]
The best smoked fish in the world though, as kiwi will no doubt testify, is undoubtably the genuine Arbroath Smokie, a smoked haddock. There is a quarter in Arbroath, Scotland where the traditional smoking of this fish continues.

Wood work but can't!
