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 body of the dish and is cooked briefly so it stays tender.
- Onions
- Soften into a sweet, moist layer that covers and flavours the beef as it cooks.
- Salt pork
- Renders fat for frying the onions and adds savoury, smoky richness.
The step that matters
Cook quickly without scorching. The beef needs a short, fairly high-heat cook to stay tender, but sugars in the onions and fat can scorch and turn bitter if the heat is too high or the pan is left unattended.
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.
