Ahhhh - HA !!

So I was doing some research because I wanted to know how "curing meat" worked. I learned some about it ... how it works ... why it works etc ... and whilst doing this research I also happened upon the answer to another question I've had, lo, these many years ... "Why do they call corned beef, 'corned'." Mystery solv-ed.

'Salt beef' in the UK and Commonwealth as a cured and boiled foodstuff is sometimes known as 'Corned beef' elsewhere, though traditional salt beef is different in taste and preparation. The use of the term corned comes from the fact that the Middle English word corn could refer to grains of salt as well as cereal grains.
