Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheatfish
- Firm, mild white flesh that holds its shape through frying and baking in the sauce.
- Flour
- Dusting the fish helps it brown when fried and lightly thickens the sauce.
- Onion
- Softens and sweetens as it cooks, forming the base flavour of the sauce.
- Tomatoes
- Provide the main body, acidity and liquid of the sauce as it reduces.
- Oil
- Conducts heat for frying the onion and fish and carries flavour into the sauce.
The step that matters
Reducing the liquid in the oven. Fish is delicate and can dry out or fall apart if baked too long. Baking until the sauce reduces should be watched closely so the fish stays moist while the sauce thickens.
Swap the tomato
How well each one fits the dish's main ingredients (flour, onion, sugar):
- Arrowrootfits better
- Okrafits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against flour, onion, sugar. Candidates are from the same food group and used in at least 100 recipes.
