@msolga,
It's a play on words. The US has all sorts of weird Miss this and that contests. Like Miss Ohio Dairy Queen and such like.
Miss Spelt....he thought that spelt was a fish...
Actually, spelt is a grain:
spelt2
n
(Life Sciences & Allied Applications / Plants) a species of wheat, Triticum spelta, that was formerly much cultivated and was used to develop present-day cultivated wheats
[Old English; related to Old Saxon spelta, Old High German spelza]
It's just good humoured play on words Msolga.
