Wrapped Fish

Finely chop the salsa, onion, capers, and anchovies

Spread a little butter on each fish strip, add a spoonful of the seasonings, roll up and secure with a toothpick, placing the rolls in a greased baking dish

Make the sauce by dissolving the flour in milk and cooking it over low heat, stirring well until thickened

Once removed from the heat, mix in the egg yolk and a little of the seasonings, pour over the fish rolls and bake in a hot oven for 30 minutes.
