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 ↓
Fowl Ragout
Ingredients
Directions
Brown the fowl
Heat the butter or fat in a stewpan.
Fry the fowl pieces until nicely browned, then remove and keep warm.
Fry the onion slightly in the same pan.
Make the sauce
Sprinkle in the flour and cook slowly until well browned.
Add the stock and stir until boiling.
Season with salt and pepper, then return the fowl to the pan.
Add the diced ham or bacon and cover closely.
Simmer and serve
Cook gently for 1 to 1½ hours, or until the fowl is tender.
Serve with the sauce strained over the fowl.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main meat, which becomes tender through slow gentle cooking in the sauce.
- Butter or good fat
- Carries the browning of the fowl and adds richness and flavour to the pan.
- Flour
- Thickens the stock into a sauce once cooked until browned.
- Stock
- Forms the liquid base of the ragout that the flour thickens.
- Ham or bacon
- Adds salty, savoury flavour to the sauce during the long covered cooking.
- Onion
- Adds aromatic sweetness and depth to the sauce base.
The step that matters
Cooking the flour until well browned. Browning the flour in the fat develops a nutty, deeper colour and flavour and removes raw floury taste. Stopping early leaves the sauce pale and pasty, while cooking too fast can scorch it before the sauce is properly developed.
Swap the onion
How well each one fits the dish's main ingredients (ham, butter, flour, pepper):
- Shallotfits better
- Okrafits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against ham, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
