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 ↓
Fish Chowder
Ingredients
Directions
Prepare
Slice the fish, potatoes, and onion.
Cut the salt pork into half-inch squares.
Make the chowder
Fry the pork and onions in a saucepan until light brown.
Add the claret and bring to a boil, then remove from heat.
Butter a large stew-pan and layer the potatoes, fish, onions, and pork, seasoning with pepper and salt.
Pour the claret over the layers and barely cover with boiling water.
Cover and simmer for 15 minutes without disturbing.
Finish and serve
Boil the milk (or cream), then remove from heat and stir in the butter and ship crackers.
Arrange the fish and potatoes in a dome shape on a hot platter.
Top with the softened crackers and pour the milk mixture over.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder and flakes into tender pieces as it cooks.
- Potatoes
- Add starch and body, helping thicken the broth and give the chowder substance.
- Salt pork
- Renders fat and savoury flavour into the dish as it fries with the onions.
- Claret
- Adds acidity and wine flavour to the broth as it simmers with the layers.
- Milk
- Enriches the finishing sauce with richness and a creamy, smooth texture.
- Ship crackers
- Soften in the hot milk and butter, thickening the topping and absorbing liquid.
The step that matters
Simmer without disturbing. Once the layers are covered with boiling water, stirring or lifting them can break up the fish and potatoes. Leaving them undisturbed lets the fish cook gently into large, intact pieces.
