Homemade crawfish/shrimp seasoning recipe?

I haven't tried either of these but I found them in my database.

Louisiana Shrimp Boil

2 parts each:
coriander seeds
mustard seeds
dill seeds
1 part each:
celery seeds
whole cloves
whole allspice
black peppercorns
dried red chilies
*
1 hand-full of bay leaves
a few quartered yellow onions
a few lemons & oranges, quartered
a generous and seemingly diabolical amount of salt

In a large pot mix together about one cup of the seasoning blend with one gallon of fresh cold water. With a spoon taste the broth and adjust the flavors accordingly, now and later on before you add the goods, keeping in mind that it has to be very strong: The saltiness countering the sweet/sourness of the citrus, the various seasonings being in balance. Bring to a boil and then simmer for 45 minutes. Strain out the seasonings and return the flavored liquid to the pot; Or, just keep the seasoning mix bundled up in cheese cloth. Return to a hard boil and add some whole shrimp. Remove them from the pot just as the liquid is returning to a boil. Now the pot is seasoned wonderfully with the spices, the citrus and the shrimp. Boil potatoes, corn, artichoke, eggs. Andouille, cabbage, green onion heads..all are great additions. I have found it beneficial to hold the boiled goodies in a little bit of the boiling broth. Keeps everything moist and flavorful.

Cajun Boil

4 Tbs yellow mustard seeds
3 Tbs coriander seeds
2 Tbs whole allspice
2 Tbs dill seeds
1 tsp whole cloves
1 Tbs crushed red pepper
8 bay leaves
Salt and cayenne pepper (or liquid hot sauce) to taste

Combine all dry ingredients thoroughly. Place in a square of muslin or cheesecloth and tie securely with string, like a large sachet d'ipices. Add salt and cayenne or hot sauce to taste. When water for seafood is boiling, add the bag and boil for several minutes, until the boiling liquid is tinted and seasoned, then add shellfish and cook until done, depending on what you're using.
