Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin or tender round steak
- Forms the main meat that is cooked and served under the onions.
- Onions
- Soften into a sweet, moist layer that covers and flavors the beef.
- Salt pork
- Renders fat into the skillet to cook the onions and add savory flavor.
- Butter
- Adds richness and flavor when placed over the finished dish.
The step that matters
Cover and cook quickly without scorching. Onions and meat contain sugars and proteins that brown and burn quickly over direct heat. Keeping the lid on traps moisture for gentle steaming, so a quick cook without scorching depends on watching the heat closely.
Swap the onion
How well each one fits the dish's main ingredients (pork, butter):
- Potatofits better
- Onionthe original
- Asparagusfits less well
- Capsicumfits less well
Fit is the average pairing score against pork, butter. Candidates are from the same food group and used in at least 100 recipes.
