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
Heat the butter in a stewpan over medium heat.
Brown the fowl pieces in the butter, then remove and keep warm.
Sauté the onion until slightly softened.

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, covered cooking in the sauce.
- Flour
- Cooked in the butter to form a roux that thickens the stock into a sauce.
- Butter
- Carries the browning of the fowl and onion and adds richness to the sauce.
- Stock
- Forms the liquid base of the sauce, which thickens as it boils and reduces.
- Ham or bacon
- Adds savoury, salty flavour to the sauce during the long gentle cooking.
- Onion
- Adds aromatic sweetness and depth as it softens in the butter.
The step that matters
Cooking the flour until browned. Flour cooked in fat must be stirred and cooked slowly until browned. Browning develops nutty flavour and colour, and undercooked flour leaves a raw, pasty taste and weak thickening.
