I bought my first pot and burner to start hosting crawfish boils in Huntsville, AL. After reading several recommendations on this board I got the double jet burner
and the 100 qt cajun rocket pot
I've boiled crawfish many times, but I've got to say I was a little nervous boiling with this gear for the first time for all of my buddies up hear, most of which are crawfish boil virgins.
I've never timed how long it takes to bring the pot of water up to its initial boil, nor have I ever timed how long it takes to bring the water back to a rolling boil after you drop the crawfish. But with a single jet burner and a normal pot it feels like it usually takes a while.
...not with this rig...
Initial rolling boil - 8 min
Time to rolling boil after dropping crawfish - 5 min
Some might say, what's the rush? You have less time to drink beer, etc. However, all of the time you save during the boiling process, you can choose to make up by soaking the crawfish longer on the back end of the boil (which we did) without worrying about overcooking the crawfish. Overall I think this puts you in greater control for how long you want the process to take, and since the burner is on for a shorter period of time you don't have to scream over each other to carry on a conversation as long. I can also see this rig being a huge advantage when you are boiling multiple batches with one pot.
Anyway, all of that to say, my hat is off to the food and drink board for some excellent recommendations.
My boils are forever pimped!
