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 and Onions
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a large skillet, melt the butter over medium heat.
Add the rabbit pieces and brown them on all sides.
Add the sliced onions and cook until they are soft.
Season with salt and pepper.
Cover and simmer until the rabbit is cooked through, about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the main protein, which firms and turns opaque as it cooks through.
- Onions
- Soften and sweeten as they cook, adding body and savoury flavour to the pan.
- Butter
- Carries heat into the pan and adds fat and richness for browning the rabbit.
The step that matters
Browning the rabbit on all sides. Searing creates browned flavour through the Maillard reaction. Crowding the pan or moving the pieces too early traps moisture and steams the meat instead, leaving it pale and less flavourful.
