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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the main meat, which becomes tender and savory when cooked through in fat.
- Onion
- Softens in the hot lard and adds sweetness and aroma to the base of the dish.
- Lard
- Fat that carries the heat and flavor of the onion and beef.
- Potatoes
- Boiled until tender and mashed, they give the dish its soft, starchy side.
- Flour
- Thickens the cooking juices into a gravy.
The step that matters
Thickening the gravy with flour. Flour must be cooked or whisked into the strained juices so it dissolves smoothly; added in lumps or without heat, it stays raw-tasting and grainy instead of thickening evenly.
