Why it works: Potato and onion match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 9,019 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Layer
In a kettle, layer bacon and meats, seasoning each layer.
Dredge with flour, then add a layer of potatoes and onions.
Repeat layers until the kettle is nearly full.
Stew
Pour enough broth or water to cover the ingredients.
Stew slowly for 1 to 3 hours, depending on the size of the meat.
During the last hour, stir in 1 quart of batter to thicken.
Season to taste and serve hot.

Flour and onion share little aroma chemistry, yet 31,198 recipes mention both: they likely 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
- Various meats
- Provide the main protein and rich flavor that the stew is built around.
- Flour
- Coats the meat and helps thicken the stew liquid as it cooks.
- Potatoes
- Add starch and body, softening into the stew as it simmers.
- Onions
- Contribute sweetness and aroma as they cook down into the stew.
- Batter
- Thickens the stewing liquid when stirred in near the end of cooking.
The step that matters
Stew slowly. Gentle, long simmering lets tough meats become tender without drying out or scorching on the bottom. Too much heat can toughen the meat and burn the stew, so keep it at a low, steady simmer for the full time, which depends on the meat size.

Fit is the average pairing score against meat, flour, potato. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
