Why it works: Rabbit and onion are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,292 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
To Boil Rabbits Whole
Ingredients
Directions
Prepare
Wash the rabbits well and soak them in warm salt water for 30 minutes.
Truss the rabbits by cutting the sinews under the back legs and bringing them flat to the side, fastening with a skewer.
Bring the head around to the left side and secure it with a skewer through the right foreleg and body.
Tie a piece of string around the skewers under the rabbit to maintain its shape while cooking.
Cook and serve
Place the rabbits in boiling water and boil slowly for 1 hour.
When serving, position the heads of the rabbits in opposite directions and cover with onion sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbits
- Provides the main meat, which stays tender and moist when simmered gently.
- Onion sauce
- Coats the cooked rabbit, adding moisture and savoury onion flavour.
The step that matters
Boil slowly for 1 hour. A rapid, rolling boil toughens the meat and can break the rabbits apart. A gentle simmer cooks the proteins evenly, keeping the meat tender and the bodies intact.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, sauce):
- Mustardfits better
- Shallotfits better
- Welsh onionfits about as well
- Onionthe original
Fit is the average pairing score against rabbit, sauce. Candidates are from the same food group and used in at least 100 recipes.
