A very entertaining puzzle this week, I thought. There were plenty of unfamiliar terms and spellings, though they were all well signposted, meaning that while a fair bit of confirmation was needed from Chambers, I managed this in one sitting.

I’m not entirely certain I’ve identified the correct fish/grain combination at 16 down, so I’ve reproduced the clue in case readers have a better suggestion.
