Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Old-fashioned Pot Roast
Ingredients
Directions
Marinate
In a deep bowl, combine sliced onions, salad oil, salt, pepper, garlic, and vinegar.
Add the beef and let it marinate for 8 hours.
Brown and cook
Preheat an old-fashioned iron pot until intensely hot.
Place bacon slices in the bottom.
Remove the beef from the marinate and brown it thoroughly on one side, then turn and brown the other side.
After browning, add the tomatoes, carrots, remaining marinate, parsley, and celery to the pot.
Once cooked, remove the meat and mash the vegetables and gravy together.
Serve
Serve the meat garnished with fried onions and the gravy on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Forms the main body of the dish; long cooking in liquid makes it tender.
- Vinegar
- Acidity in the marinade helps tenderize the meat's surface.
- Tomatoes
- Add acidity and body to the braising liquid that becomes the gravy.
- Bacon
- Its fat renders into the pot, adding richness and browning for the sauce.
- Carrots
- Add sweetness and body to the vegetables that are mashed into the gravy.
The step that matters
Browning the beef thoroughly. Deep browning builds caramelized, savory flavor through the Maillard reaction. Pale or uneven searing leaves the gravy flat, so the meat should be dry and the pot very hot before it goes in.
Swap the clove
How well each one fits the dish's main ingredients (beef, onion, pepper, garlic, vinegar, tomato, carrot):
- Cuminfits better
- Parsleyfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against beef, onion, pepper, garlic, vinegar, tomato, carrot. Candidates are from the same food group and used in at least 100 recipes.
