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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that flavours the milk and the layers of potato and fish.
- Sliced potatoes
- Absorb the milk and soften, thickening the chowder body.
- Fish
- Provides the main protein and flavour, cooking gently in the milk.
- Pilot crackers
- Soak up liquid and help thicken the chowder.
- Milk
- Forms the creamy liquid that cooks the layers and gives body.
- Sliced onions
- Add sweetness and aroma as they soften slowly in the liquid.
The step that matters
Cook very slowly. Milk scorches and can curdle or boil over if heated quickly. A gentle, low heat lets the potatoes and fish cook through while the milk stays smooth and creamy.
