re: Anyone make their own Crawfish Seasoning?

This is Alton Brown's spice mixture for 10 lbs of crawfish.
I've never used it, so I can't vouch.
I hear it could use more cayenne.

1 tablespoon whole black peppercorns
1 tablespoon whole coriander seeds
2 tablespoons whole cloves
1 1/2 tablespoons whole allspice
1 pound kosher salt
4 tablespoons cayenne pepper
2 tablespoons garlic powder
2 tablespoons paprika
1 tablespoon onion powder
1 tablespoon dried thyme
1 tablespoon dried oregano
1 tablespoon dry mustard
1 tablespoon dried dill weed
6 bay leaves, crumbled

He grinds the first four.
