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 of
Ingredients
Directions
Prepare the sauce
Heat the butter in a stewpan.
Fry the fowl pieces until nicely browned, then remove and keep warm.
Fry the onion until slightly softened.
Sprinkle in the flour and cook slowly until well browned.
Add the stock and stir until boiling, then season with salt and pepper.
Braise and serve
Return the fowl to the pan, add the ham or bacon, and cover closely.
Cook gently for 1 to 1½ hours, or until the fowl is tender.
Serve with the sauce strained over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Its meat becomes tender and flavourful during the long, gentle braise.
- Flour
- Cooked in the butter until browned, it thickens the stock into a rich sauce.
- Butter
- Carries the frying and adds rich flavour to the browned base of the sauce.
- Ham or bacon
- Adds savoury, salty flavour that seasons the sauce and meat during cooking.
- Onion
- Softened in the fat, it adds sweetness and aromatic depth to the sauce.
- Stock
- Forms the liquid base of the sauce and gives the braise its body.
The step that matters
Browning the flour. Cooking the flour slowly in the fat until well browned toasts it and removes raw starch taste, giving the sauce deeper colour and flavour before the stock is added and lumps can form if rushed.
Swap the onion
How well each one fits the dish's main ingredients (ham, butter, flour, pepper):
