Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Stew
Ingredients
Directions
Prepare the jar
Layer sliced onions and rabbit pieces alternately in a deep earthenware jar. Season each layer with a little coarse sea salt and black pepper.
Top with slices of bacon.
Cover the jar securely with greased paper.
Cook
Place the jar in a saucepan of boiling water, almost up to its neck. Boil for 2.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbits
- Provide the main meat, which becomes tender during the long, gentle cooking.
- Onions
- Add sweetness and moisture as they soften and release juices into the stew.
- Bacon
- Adds fat and savoury flavour that seasons the meat and onions as it cooks.
The step that matters
Keeping the jar sealed and the water at a steady boil. The greased paper traps steam so the rabbit cooks in its own juices rather than drying out. If the cover is loose or the water boils dry, the meat can toughen or lose moisture over the 2.5 hours.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, pepper):

Fit is the average pairing score against rabbit, pepper. Candidates are from the same food group and used in at least 100 recipes.
