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
Take a deep earthenware jar.
Fill the jar with alternating layers of sliced onion and rabbit, seasoning each layer with pepper and coarse sea salt.
Lay slices of bacon on the topmost layer.
Cover the jar securely with two or three folds of greased paper.
Cook
Place the jar, almost up to its neck, in a saucepan of boiling water.
Keep it boiling for two and a half hours.
The onions will provide enough moisture to stew the rabbit and serve as gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the meat that becomes tender as it stews slowly in its own juices.
- Sliced onion
- Releases moisture as it cooks, stewing the rabbit and forming the gravy.
- Slices of bacon
- Lays fat over the top layer, adding richness and savoury flavour as it cooks.
