Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Thin slices cook through quickly and become tender with gentle simmering in the covered pan.
- Butter
- Fat that coats the pan and helps prevent the meat and onion from sticking as they start to cook.
- Onion
- Adds savory sweetness and aroma as it softens and releases its juices into the pan.
- Apple
- Finely minced apple softens into the juices, adding gentle sweetness and a touch of acidity.
The step that matters
Simmer covered until very tender. Beef is tough and needs low, moist heat over a long enough time for its connective tissue to break down. Keeping the lid on traps steam so the meat stays moist, while too much heat can toughen it. Check that the meat is fully tender before serving.
