Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Directions
In a pot, fry the salt pork until brown.
Add the chopped onions and a layer of haddock on top.
Sprinkle with bread crumbs and add a layer of sliced potatoes.

When nearly done, add the milk and let it scald.
Just before serving, stir in the tomato ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main flaky, tender body of the chowder as it cooks.
- Salt pork
- Adds savory fat and browned flavor to the pot.
- Potatoes
- Add starch that thickens the broth and gives body to the chowder.
- Milk
- Adds creaminess and richness to the broth once it is scalded.
- Bread crumbs
- Help thicken the broth and soften into the chowder.
- Tomato ketchup
- Adds sweetness, acidity and a tangy reddish tint to the finished chowder.
The step that matters
Let the milk scald without boiling. Milk can curdle or separate when it boils hard, especially in an acidic or salty broth. Adding it near the end and heating it gently keeps the chowder smooth and creamy.
