Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potato Stew
Ingredients
Directions
Prepare

Stew
Layer some potatoes in a saucepan, followed by onions, pepper, and salt; repeat until all ingredients are used.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the stew and soften into a tender, starchy body as they cook.
- Onions
- Add sweetness and savour that deepens during slow stewing.
- Milk
- Adds richness and creaminess to the stewing liquid.
- Sweet cheese
- Melts and browns under the broiler, adding a golden crust and savoury flavour.
The step that matters
Browning under the broiler. Cheese can burn quickly under high heat, while milk-based dishes can scorch or curdle if overheated. Watch closely so the cheese browns evenly without the dish drying out or the sauce separating.
Swap the onion
How well each one fits the dish's main ingredients (potato, milk, cheese, butter, pepper, parsley):
- Capsicumfits better

- Chivefits about as well
- Onionthe original
Fit is the average pairing score against potato, milk, cheese, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
