Will cook dry quickly. Be careful.
I found this out the hard way. Bought a Bayou double jet burner, placed my keg on top with water and vinegar mix, cranked the regulator up all the way. Pot started steaming in no time, added crabs and JO then got side tracked doing something. Came back when the crabs should have been ready to find smoke rolling out of the pot. Didn't burn through the keg but had a heck of a mess to clean up and a new meaning to Blackend Crabs.
Now I crank it up until it steams then turn it back down .
