Why it works: Onion and potato 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 the base
Fry the salt pork with the chopped onion until brown.
In a kettle, combine the fried pork and onion with the fish and cover with boiling water.
Add a little coarse sea salt and cook until the fish is tender.
Finish the chowder
Add the cooked sliced potatoes to the chowder along with the milk.
Melt the butter in a pan, stir in the flour, and gradually add 1 cup of the hot liquid to make a sauce.
Stir the sauce into the chowder and season with pepper and salt to taste.
Top with a few crackers before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat and browns, adding savory flavor to the chowder base.
- Butter
- Adds richness and fat, and with the flour forms the thickening sauce.
- Flour
- Thickens the butter and liquid into a sauce that gives the chowder body.
- Milk
- Adds creaminess and moisture, softening the chowder's texture.
- Potatoes
- Add starch and bulk, making the chowder heartier and slightly thicker.
The step that matters
Stirring the flour sauce into the chowder. Flour thickens best when it is cooked in fat and whisked into hot liquid gradually, which prevents lumps. Adding it all at once or to cold liquid can leave clumps that do not smooth out.
