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 ↓
Lamb Stew
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a large pot, combine lamb, potatoes, onions, and water.
Bring to a boil, then reduce heat and simmer for 1.5 hours.
Season with salt and pepper to taste before serving.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Provides the main protein; long simmering breaks down connective tissue, making the meat tender.
- Potatoes
- Add body to the broth as their starch releases and softens during simmering.
- Onion
- Adds aromatic sweetness and depth to the broth as it cooks down.
The step that matters
Simmer gently after boiling. Once the pot boils, reducing the heat to a simmer keeps the liquid from churning hard. A gentle simmer lets the lamb turn tender without toughening the meat or breaking up the potatoes too quickly.
Swap the onion
How well each one fits the dish's main ingredients (lamb, potato, pepper):
- Spinachfits better
- Asparagusfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against lamb, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
