Soft Roes on toast

When I was a boy every Friday we had Soft Roes on toast for breakfast. What a treat! Soft roes are Herring roe rolled in flour and then fried and, on my culinary Richter scale, they rate a 10. Not only are they absolutely delicious but they are dirt cheap. And that is the problem. No fishmonger in Exeter is selling them anymore. Sainsbury's fish counter did for a long time but then gave up as 'there is no demand' (groan) - then I had a brainwave -surely - I thought- that new Waitrose would stock them - no luck there either.  So my quest continues and will end - I suspect -in finding some fishmonger who will dispatch them by post.
