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

What each ingredient does

Catfish fillets: Provides the protein that cooks gently in the trapped steam, staying moist and flaky.
Butter: Adds fat that carries flavor and keeps the fish moist as it steams.
White wine: Creates steam with the butter and adds acidity that brightens the fish and vegetables.
Zucchini: Releases moisture inside the packet, helping steam the fish while staying tender-crisp.
Carrot: Adds subtle sweetness and a firm texture that holds up during steaming.
Fresh herbs: Contribute aroma that perfumes the steam and seasons the fish.

The step that matters

Sealing the packets completely. If the edges leak, steam escapes and the fish steams less evenly and can dry out. Tight crimping keeps the moisture and heat inside so the fish cooks gently and evenly.
