Salmon, prawn and cucumber pie is one of the several Slater variations on fish baked in lightly flavored cream topped with bread crumbs or a crumble. Find it at http://cooks.ndtv.com/article/show/ni... and other locations.
Really a 1-2-3 preparation. The only suggestion I would have is if your cream is not pretty thick salt rinse and pat dry the cucumber slices. Since this is a naked recipe use the freshest fish you can get and cook to the specified time.
The result is pure flavors a touch of richness and a breath of perfume. I have had this one over six times in as many months.
