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 ↓
Another Wat to Stew Onions
Ingredients
Directions
Roast the onions
Peel the onions and roast them in a Dutch oven, turning frequently until well browned.
Stew
Transfer the browned onions to a saucepan with the meat bone, bacon, water, and pepper.
Cover the pan and stew until the onions are tender.
Remove the bone and bacon from the pan.
Thicken and finish
Thicken the sauce by rolling the butter in flour and adding it to the pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Become sweet and soft when browned and stewed, forming the body of the dish.
- Butter
- Combined with flour to form a roux-like paste that thickens the sauce.
- Flour
- Thickens the cooking liquid when mixed with butter and added to the pan.
- Bacon
- Adds savory, smoky fat and flavor to the stewing liquid.
The step that matters
Roasting the onions until well browned. Browning triggers the Maillard reaction and caramelization, which build the deep, sweet flavor the stew depends on. Pale onions will taste flat and boiled.
Swap the onion
How well each one fits the dish's main ingredients (meat, pepper, butter, flour):
- Shallotfits better
- Potatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against meat, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
