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 Chowder
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.
Prepare
Preheat the oven to 400°F (200°C).
Assemble and cook
Layer the salt fish, onion, potatoes, and crushed cracker in a buttered baking dish.
Season with salt and cayenne pepper.
Pour hot water over the layers and boil gently for 20 minutes.
Add hot milk and cream, then bring to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Provides the main savoury, salty flavour that defines the chowder.
- Raw potatoes
- Starch that softens during simmering and helps thicken the chowder.
- White onion
- Adds sweetness and aroma as it softens in the liquid.
- Cracker
- Crushed crumbs absorb liquid and help thicken the broth.
- Milk
- Adds richness and creaminess to the liquid base.
The step that matters
Boiling gently after adding the hot water. A gentle simmer cooks the potatoes through without breaking them apart. A hard boil can break down the starch and make the chowder cloudy or ragged. Adding the milk and cream later and bringing it to a boil only briefly keeps the dairy from curdling or scorching.
