Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Barley Stew
Ingredients
Directions
Prepare
Cut the meat into small pieces.
In a large saucepan, combine the meat, onions, barley, and water.
Simmer the stew
Bring to a boil slowly, skimming the stew as it begins to boil.
Reduce heat to a simmer and cook for 3 hours.
Mix the flour with a little cold water, then add it to the stew along with the potatoes, salt, and pepper.
Simmer for an additional hour.
For added flavor, stir in pieces of stale bread during the last 10 minutes of cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the stew as it cooks and adds a chewy texture.
- Meat
- Provides savory flavor and richness to the broth.
- Onions
- Add sweetness and aroma as they soften in the broth.
- Potatoes
- Add body and starch that helps thicken the stew.
- Flour
- Thickens the broth when mixed with cold water before adding.
The step that matters
Skimming while bringing to a boil. Bringing the stew to a boil slowly and skimming foam keeps the broth clear and removes impurities that would otherwise cloud the stew and taste bitter.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, barley, pepper, flour):
