Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 350°F (175°C).
Prepare the stuffing by mixing bread crumbs, oil, sliced onion, sage, celery, and parsley.

Stuff and bake

Fill the cleaned mackerel with the stuffing.
Place the stuffed mackerel in a baking pan and cover with strips of salt pork.
Bake for 20 to 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Spanish mackerel: Forms the main body of the dish, holding the stuffing as it bakes.
Bread crumbs: Absorb the oil and onion juices, forming a moist stuffing that keeps the fish tender.
Salt pork: Renders fat over the fish, adding moisture and savory flavor as it bakes.
Oil: Coats the bread crumbs, adding richness and moisture to the stuffing.
