Zatarain's is good, but personally I like...
Louisian Fish Fry

They make several blends for frying, but I like to mix the
Fish Fry with the Shrimp Fry for just about any kind of
fish or seafood. About a 50/50 mix.

Then you can add Tony's for that spicy taste.

Just remember, with Tony's, you DON'T need to add salt or pepper.

Slap yo momma spice and cayenne pepper
