This is so so yummy! I've been making this for a long time for my family and although smoked salmon is perceived as an expensive item, for around the £3 it costs me to buy the salmon I can make enough of this for around 10 sandwiches, not that it ever lasts that long. It goes ALOT further that the equivalent smoked salmon pate in any supermarket!
For a cheaper alternative why the follow the recipe but use mackerel instead.
if you use mackerel change the mustard for horseradish. yum!
