I used the recipe our Swedish branch of the family use and I have to say it was delicious, a very intense flavour but not recognisably fishy at all, the small soft fish fillets had totally dissolved and melted into the potatoes and cream, they're quite different to our anchovies. My other half hates anchovies with a passion and approached this will some suspicion but he too thought it was lovely which i was quite surprised about. It's like a very, very savoury dauphinoise. Rocky, I'm sure it would go down a storm on your international night.
