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 ↓
Marseilles Fish-stew
Ingredients
Directions
Prepare the stew
Scale, clean, and wash the fish, then cut them into pieces.
In a stewpan, heat oil and add the sliced onions; simmer without browning.
Add the fish, herbs, cloves, peppercorns, coarse sea salt, garlic, and tomatoes, layering them.
Moisten with more oil and fill the stewpan with water, ensuring enough liquid for the stew.
Cover and boil for one hour, tasting the broth and adjusting seasoning as needed.
Serve
Once cooked, garnish the bottom of a soup dish with slices of bread, pour some broth over it, and arrange the fish on top.
Add more slices of bread over the fish and pour the remaining broth on top before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main body and flavor of the stew as it breaks down into the broth.
- Onions
- Softened slowly in oil without browning, they add sweetness and a mellow base to the broth.
- Tomatoes
- Add acidity and body, giving the broth its color and savory depth.
- Garlic
- Contributes pungent aroma that mellows and deepens during the long simmer.
- Bread
- Soaks up the broth when layered in the dish, adding body and texture to the serving.
The step that matters
Simmer the onions without browning. Browned onions turn bitter and darken the broth, while gently softened onions release sweetness and build a mild, clean base for the stew.
Swap the clove
How well each one fits the dish's main ingredients (whiting, onion, garlic, tomato, bread):
- Capersfits better
- Parsleyfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against whiting, onion, garlic, tomato, bread. Candidates are from the same food group and used in at least 100 recipes.
