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 ↓
Broiled Steak, with Bordelaise Sauce
Ingredients
Directions
Cook the steak
Preheat the broiler over hot coals or a very hot stove.
Beat the round steak until tender and place it on the broiler.
Cook until brown on one side, then turn and cook the other side until done.
Transfer the steak to a hot platter and spread with hot melted butter, then sprinkle with salt and pepper.
Make the sauce
For the sauce, chop the onion finely and fry in butter until light brown.
Mash the tomatoes through a sieve and add to the onions.
When boiling, stir in chopped garlic, salt, and pepper.
Cook for 15 minutes and serve over the steak or separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Is the main protein; beating it breaks up fibers so it becomes more tender.
- Butter
- Adds richness and a glossy coating to the steak, and browns the onions for the sauce.
- Onion
- Fried until light brown, it adds sweetness and savory depth to the sauce.
- Ripe tomatoes
- Mashed into a sieved pulp, they form the body and bright acidity of the sauce.
- Garlic
- Adds pungent aroma that mellows as the sauce cooks.
The step that matters
Cook the steak until brown on one side, then turn. Searing under intense heat browns the surface through the Maillard reaction, building flavor. Turning only once and cooking to doneness keeps the interior from overcooking while the outside stays browned.
Swap the clove
How well each one fits the dish's main ingredients (butter, pepper, onion, tomato, garlic):
- Thymefits better
- Parsleyfits better
- Cuminfits better
- Clovethe original
Fit is the average pairing score against butter, pepper, onion, tomato, garlic. Candidates are from the same food group and used in at least 100 recipes.
