Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Spanish Stew
Ingredients
Directions
Prepare
Cut the cold beef into small pieces.
In a stew pan, combine the beef, tomatoes, onions, and macaroni.
Cook and finish
Cover and cook for 3-4 hours until the meat is reduced to shreds.

Season highly before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Slow cooking breaks the meat down into shreds that give the stew its body.
- Macaroni
- Starch from the broken pasta thickens the gravy as it cooks down.
- Tomatoes
- Adds acidity and liquid that form the base of the gravy.
- Onions
- Soften during long cooking, adding sweetness and depth to the gravy.
The step that matters
Adding boiling water to the gravy. If the gravy boils away, the stew can become dry and over-concentrated. Adding boiling water rather than cold keeps the cooking temperature steady and loosens the gravy without stopping the simmer.
