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 ↓
Stewed Ox Heart and Liver
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Wash the ox heart well.
Mix chopped onions, sage, 1 teaspoon salt, and ¼ teaspoon pepper with the heart.
Place the heart in a pan with the top part downwards.
Layer and bake
Add suet pieces, ox liver, and bacon if using.
Season with 3 teaspoons salt, 1 teaspoon pepper, chopped onions, and potatoes.
Pour 3 quarts of water over the mixture.
Bake in a 350°F (175°C) oven for 3 hours.

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, slow cooking in liquid.
- Suet
- Adds fat that enriches the stew and keeps the meat moist during the long bake.
- Ox liver
- Contributes a rich, deep flavor and a soft, creamy texture to the stew.
- Potatoes
- Their starch softens and thickens the cooking liquid, giving the stew body.
- Onions
- Soften and turn sweet as they cook, adding depth and aroma to the broth.
The step that matters
Bake low and slow for the full 3 hours. Ox heart is tough connective tissue. A steady 350°F oven breaks it down gradually into tender meat while the water keeps the stew from drying out. Rushing with higher heat can leave the meat chewy.
