Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Rabbit, Smothered with Onions
Ingredients
Directions
Prepare the rabbit
Truss the rabbit firmly and dry it well.
In a saucepan, bring 3 quarts of water to a boil and add the rabbit.
Simmer gently until the rabbit and onions are cooked through.
Make the onion sauce
Remove the onions, mince them, and place in a clean saucepan.
Add butter, flour, milk, and white pepper to the minced onions. Mix thoroughly over gentle heat to form a puree.
Serve
Place the rabbit on a hot dish, remove the skewers, and pour the onion puree over it. Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the main meat, which cooks through during gentle simmering.
- Large onions
- Break down into a puree that thickens and sweetens the dish.
- Butter
- Adds richness and a smooth, rounded flavour to the onion puree.
- Flour
- Thickens the onion puree so it clings to the rabbit.
The step that matters
Mixing the onion puree over gentle heat. Flour thickens best when it is evenly mixed into the onions and heated gently; high heat can scorch the butter and onions or leave the sauce lumpy.
Swap the white pepper
How well each one fits the dish's main ingredients (rabbit, onion, butter, flour, milk):
- Garlicfits better
- Capersfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against rabbit, onion, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
