Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Red Snapper, or Sheep's-head
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Boil the potatoes until tender, then mash them with butter, onion, black pepper, and salt.
Bake the fish
Salt the fish and place it in a baking pan.
Stuff the fish with the potato mixture and sprinkle a little flour over it.
Add butter, sweet oil, sliced tomatoes, and water to the pan with the fish.
Bake in a moderate oven (350°F / 175°C) until the fish is done.
Finish and serve
Once cooked, slice the hard boiled eggs over the fish.
Stir tomato ketchup and Worcestershire sauce into the gravy and pour it over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red snapper or sheep's-head
- Main protein that firms and turns opaque as it bakes through.
- Irish potatoes
- Starchy mash that binds the stuffing and absorbs the juices from the fish.
- Butter
- Adds fat and richness to the stuffing and the pan gravy.
- Sweet oil
- Adds fat that keeps the fish moist in the oven.
- Tomatoes
- Provide acidity and liquid that build the savoury gravy in the pan.
The step that matters
Bake until the fish is done. Fish cooks quickly and turns dry and tough once overcooked, so check it for flaking at the thickest part. The sauce and moist pan help protect it during baking.
