Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Catfish fillets: Provide the main protein, which cooks quickly in the sauce and stays tender when handled gently.
Whipping cream: Adds richness and body, helping the sauce become smooth and coat the pasta.
Milk: Thins the cream into a looser sauce while adding dairy flavor and body.
Dry white wine: Adds acidity and aromatic depth that balances the rich dairy in the sauce.
Butter: Adds fat and flavor to the pan base for cooking the onions and pepper.
Fettuccine: Carries the sauce and gives the dish its body as the base starch.

The step that matters

Stirring while the sauce thickens. Cream-based sauces can scorch on the bottom of the pan or curdle if overheated. Constant stirring over medium heat keeps the dairy evenly heated and lets it thicken smoothly.
