Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbits
- Provide the main meat, which becomes tender through slow stewing.
- Onions
- Add sweetness and soften into the stew, adding body to the sauce.
- Butter and flour
- Form a roux that thickens the white stock into a smooth sauce.
- White stock
- Forms the cooking liquid that moistens and flavors the rabbit.
The step that matters
Letting the rabbits stew until tender. Rabbit is lean and its connective tissue needs long, gentle simmering in liquid to break down. Stopping early leaves meat tough, while a hard boil can toughen it and dry the surface.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, butter, flour, pepper):
