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 ↓

Ingredients
Directions
Make the soup
Heat oil in a large pot.
Saute garlic slices and chopped marjoram 2 minutes.
Add the onion slices and cook about 5 minutes (or longer if you like them very soft).
Add wine and broth and cook, uncovered, 10 minutes at a gentle simmer (bubbling, but not boiling).
Test soup- season well with salt and pepper.
Soup is ready when onions are tender- broth will be very clear & pinkish in color.
Make the toasts
Meanwhile, heat up your broiler and line a baking sheet with foil.
Using a 6 cm round biscuit cutter, cut bread slices into rounds (discard excess)- you may also use a glass.
Set bread rounds on foil lined pan and sprinkle with cheese and broil only about 1 minute- just to melt cheese.
Serve
Ladle into bowls and float a bread round on top of each bowlful, garnishing with some extra fresh marjoram if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they cook slowly, forming the body of the soup.
- Red onions
- Add sweetness and deeper colour to the soup as they soften.
- Garlic
- Adds aroma that deepens as it gently sautés in the oil.
- Dry white wine
- Adds acidity and aromatic depth to the broth as it simmers.
- Chicken broth
- Provides the liquid base that carries the flavour of the soup.
- Parmesan cheese
- Melts over the bread rounds, adding savoury richness and browning.
The step that matters
Simmer gently, do not boil. A gentle simmer lets the broth clarify and keeps the onions tender. A hard boil makes the liquid cloudy and can toughen the onions and evaporate flavour too quickly.
Swap the marjoram
The recipe marks marjoram as optional. How well each one fits the dish's main ingredients (onion, clove, garlic, olive, white wine, chicken, bread):
- Thymefits better
- Cuminfits about as well
- Rosemaryfits about as well
- Marjoramthe original
Fit is the average pairing score against onion, clove, garlic, olive, white wine, chicken, bread. Candidates are from the same food group and used in at least 100 recipes.
