Why it works: Ketchup and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Soles Filleted and Stewed
Ingredients
Directions
Prepare
Fillet the soles and cut them into 12 pieces.
Chop the shallots and parsley finely.
Spread the shallots and parsley in a shallow pan.
Cook
Double each fillet and arrange them in the center to form a star.
Pour the sherry over the fish and stew for 2.5 minutes on medium heat.
Turn the fish pieces and prepare the sauce mixture by combining mushroom ketchup, anchovy sauce, sugar, lemon juice, and cayenne.
Pour the sauce into the center of the pan and cook until boiling, about 2.5 minutes.
Serve
Serve the dish hot in the pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Provide the delicate white fish that forms the body of the stew.
- Sherry
- Adds acidity and aromatic depth as it stews with the fish.
- Mushroom ketchup
- Adds savoury umami depth to the sauce.
- Anchovy sauce
- Adds salty, savoury depth that rounds out the sauce.
- Shallots
- Contribute mild sweetness and aromatic flavour to the base.
The step that matters
Cooking the fish gently. Fish proteins toughen and dry out quickly under strong heat, so stewing on medium heat keeps the soles tender and moist while the sauce is added.
Swap the parsley
How well each one fits the dish's main ingredients (shallot, sherry, mushroom, ketchup, anchovy, sauce, sugar):
- Capersfits better
- Thymefits better
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against shallot, sherry, mushroom, ketchup, anchovy, sauce, sugar. Candidates are from the same food group and used in at least 100 recipes.
