Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Provides the meat that becomes tender during slow, covered cooking.
- Onions
- Soften and sweeten as they brown in butter, adding flavor to the casserole.
- Butter
- Carries the browning of the onions and adds richness.
- Potatoes
- Absorb liquid and thicken the casserole as they finish cooking.
The step that matters
Cover and cook slowly for 2 hours. Low, covered heat breaks down the connective tissue in round steak gradually. Cooking too fast or uncovered can toughen the meat and dry out the liquid before it is nearly tender.
Swap the onion
How well each one fits the dish's main ingredients (butter, potato):
- Chivefits about as well
- Onionthe original
- Asparagusfits less well
- Leekfits less well
Fit is the average pairing score against butter, potato. Candidates are from the same food group and used in at least 100 recipes.
