Well, no, the KettlePizza ISN'T as good as a WFO, but the point is that most if uscan't afford to buy or build a WFO. The KettlePizza allows us to follow the 80-20 rule: it's not 100%, but it gets one closer than just throwing a pie on a grill.
I've not had the greatest luck with it, but I haven't had oodles of opportunity to practice either.
The thing DOES work, it's relatively inexpensive, doesn't take up a lot of room, utilizes a piece of equipment that many of us already have and heats up fairly quick. Light it to cooked pie in about 45 minutes. I think that's way faster than most WFOs.
Are we chasing a chemera? I don't think so. The challenge makes the final product so much more gratifying. Would I like to have a WFO? Sure, but it'll be a long time in coming.
All the best! Tony
