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 ↓
Salt Fish Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Soak and boil the salt fish, then remove skin and bones, and cut the flesh into neat squares.
In a buttered pie dish, layer sliced potatoes, fish, hard-boiled eggs, and onions.
Season each layer with pepper and dry mustard, adding small pieces of butter throughout.
Pour a little egg sauce over the layers, then cover with pastry.
Bake in a preheated oven at 400°F (200°C) until the pastry is golden and the pie is cooked through.
Alternatively, use mashed potatoes to cover the pie instead of pastry, and omit the onions if desired.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
