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 ↓

Prepare the base
Cut the salt pork into dice and fry until crisp and brown.

Finish and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Fried until crisp, it renders fat and flavour into the chowder base.
- Fish
- Flakes into tender pieces that give the chowder its main body and substance.
- Potatoes
- Soften as they cook and thicken the broth while adding starchy body.
- Canned tomatoes
- Add acidity and sweetness that balance the rich milk and pork fat.
- Onions
- Release sweet aromatic flavour as they cook into the broth.
- Milk
- Adds creaminess and mild sweetness to the finished chowder.
The step that matters
Let the milk scald, do not boil. Milk added to a hot chowder can curdle or turn grainy if it boils hard. Heating it only until steaming keeps it smooth and creamy.
Swap the onion
