re: Sodium Free Crawfish Boil Seasoning mix

there are plenty of other salts besides sodium chloride…potassium chloride as noted above could be an option though you might want to experiment on something else first.

maybe go low-sodium instead of no- sodium…mix a few salts together and see if you get the taste you like. Boiled crawfish really does need salt.

one other option is seawater if you have access to it
