Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Forms the main protein; broiling over direct heat browns its surface and develops flavor.
- Onion
- Stewing in butter softens it and releases sweetness and aroma into the butter.
- Butter
- Carries the onion and seasoning flavors and adds richness and moisture to the steak.
- Lemon juice
- Adds acidity that brightens the rich butter and balances its fattiness.
The step that matters
Let the steak stand after covering. Resting lets juices redistribute through the meat instead of running out when cut, keeping the steak moister. Covering with a hot lid keeps it warm while it rests.
Swap the lemon
How well each one fits the dish's main ingredients (beef, onion, butter, pepper):
- Avocadofits better
- Mangofits about as well
- Lemonthe original
- Limefits about as well
Fit is the average pairing score against beef, onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
