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
Ingredients
Directions
Soak the salt fish in soft water for 1 to 3 nights, changing the water 2-3 times.
Place the soaked fish in cold or lukewarm water and bring to a boil slowly.
Simmer the fish for 30 minutes to 1.5 hours.
Remove the fish from the pot using a fish drainer, and discard any bones and skin.
Rinse the fish with 1 quart of boiling water.
Serve the fish with egg sauce, parsnips, and mashed potatoes.
For a variation, stew the fish in gravy flavored with onions or shallots, thickened with flour, butter, and cream.
