My neighbor uses mustard a lot of times. They always come out really good.

He puts a jar of candied jalapeno juice in the pot as they are are boiling.
After they are boiled, he throws the crawfish in an ice chest. Pours mustard, the jalapenos without juice, and a few small sprinkles of seasoning. shakes the ice chest a little bit. good stuff.
