Why it works: Pepper and onion 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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 in liquid.
- White stock
- Forms the cooking liquid that gently moistens and flavours the stew.
- Butter
- Adds richness and fat to the sauce, carrying flavour and smoothness.
- Flour
- Thickens the stock into a smooth, body-rich sauce when cooked with the butter.
- Onions
- Add sweetness and aroma as they soften in the stewing liquid.
The step that matters
Stirring the butter and flour into the stock. Flour clumps if added to hot liquid without being well combined with the butter first, leaving lumps in the sauce. Stirring until smooth lets the starch disperse evenly so it thickens the stock uniformly.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, butter, flour, pepper):

Fit is the average pairing score against rabbit, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
