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
In a deep earthenware jar, layer sliced onion and rabbit alternately.
Season each layer with a little pepper and coarse sea salt.
Top with slices of bacon.
Cover the jar securely with two or three folds of greased paper.
Cook
Place the jar in a saucepan of boiling water, almost up to its neck.
Boil for two and a half hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Forms the main body of the stew and becomes tender during the long slow cooking.
- Bacon
- Adds fat and savoury flavour that seeps down through the rabbit as it cooks.
- Sliced onion
- Breaks down during cooking, adding sweetness and body to the juices.
The step that matters
Sealing the jar. The greased paper cover must fit securely so steam stays inside. If it leaks, moisture escapes and the rabbit can dry out while the jar sits in the water bath.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, pepper):
