The word “omelet” is not used in the same sense as it is commonly used by the French and English, and I should be more inclined to describe this dish as “baked anchovies.”
The ingredients are 15 anchovies, 4 cooked potatoes,
Butter a pie dish and sprinkle with breadcrumbs. Arrange in the dish alternate layers of sliced potatoes and anchovies, previously cleaned, finishing with a layer of potatoes. Sprinkle the top with breadcrumbs and parsley, dot with pats of butter and brown in a moderate oven.
