Perry, I wouldn't bring a Griswold #13 anything down here - people would shoot you for it. I've never cooked a large jambalaya; I've assisted, but never had the responsibility. I've helped at benefits by taking a couple of sharp knives, and cutting veggies and meat for a couple of hours to take part of the load off the cook. A fireman I know used to do benefits for a burned childrens' retreat.
Large pots take a different technique, and filling one up with good stuff and making a mistake is expensive. A friend has a 15-gallon pot that he hasn't mastered yet, after probably 20 times cooking in it. I went to a benefit last weekend where the jambalaya was a disaster, gummy soggy rice with uncooked kernels mixed in. How do you do that? The people that get it right in a big pot, know their pot, and measure the rice and water, know how often and when to stir it, and have their timing down. Bobby Flay had an absolute failure against the Jambalaya King in New Orleans, for instance.
You would be most welcome in my home. Some day I may load up my van with my Griswold 202, hit the road, and be looking for yards to park in. I will not be up north in the winter, though!
