Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish, flaking gently into the sauce as it simmers.
- Flour
- Thickens the cooking liquid into a light sauce as it simmers.
- Butter
- Carries the initial frying and adds richness and browning to the fish and onions.
- Red wine
- Adds acidity and depth of flavour to the simmering sauce.
- Small white onions
- Soften and sweeten during frying and simmering, adding body to the stew.
The step that matters
Frying the fish and onions until golden brown. Browning through the butter creates savoury flavour compounds that carry into the sauce. Pale frying leaves the stew tasting flat, while over-browning the delicate fish can make it dry and bitter.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, mushroom, flour, pepper, lemon, red wine):
- Shallotfits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against fish, butter, mushroom, flour, pepper, lemon, red wine. Candidates are from the same food group and used in at least 100 recipes.
