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 ↓
Ox Heart Stewed
Ingredients
Directions
Prepare
Cut the ox heart into thin, long pieces.
Place the pieces in a stew pot with salt and enough liquid to cover them.
Skim off any scum or blood that rises to the surface.
Stew and finish
Add the onions, celery, and parboiled potatoes to the pot.
Stew gently until all ingredients are tender and well combined.
Before serving, mix the butter with enough flour to form a paste and add the catsup or walnut pickles.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox heart
- Provides the main meat, which becomes tender through long, gentle stewing.
- Onions
- Soften during stewing and add sweetness and savory depth to the broth.
- Potatoes
- Absorb cooking liquid and soften, thickening the stew and adding body.
- Butter and flour paste
- Stirred in before serving to thicken the stew and add richness.
- Catsup or walnut pickles
- Adds acidity and tangy flavor that balances the rich meat.
The step that matters
Skimming the surface. Scum and blood rising during the first simmer can cloud the broth and taint its flavor. Removing them early keeps the stew clear and clean-tasting.
Swap the walnut
How well each one fits the dish's main ingredients (onion, celery, potato, butter, flour):
- Beansfits better
- Lentilsfits better
- Chickpeafits better
- Walnutthe original
Fit is the average pairing score against onion, celery, potato, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
