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 ↓
Rabbit Smothered with Onions
Ingredients
Directions
Prepare
Stew the cleaned and trussed rabbit in water until tender.
In a separate pan, melt butter and add minced onions.
Make the onion sauce
Cook the onions until they dissolve but do not let them brown; add a little water to prevent browning.
Season with salt and pepper to taste.
Serve
Dish the rabbit and pour the onion sauce over it, ensuring there is enough sauce to smother the rabbit.

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 dish and becomes tender through slow stewing in water.
- Onions
- Dissolve into the butter to form a smooth sauce that adds sweetness and body.
- Butter
- Carries the onions and adds richness and fat to the sauce.
The step that matters
Cooking the onions without browning. Browned onions develop a different, darker flavour and colour than the pale sauce intended here. Keeping heat gentle and adding a little water helps the onions soften and break down without caramelising.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, butter, sauce, pepper):
- Mustardfits better
- Capsicumfits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against rabbit, butter, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
