Back in my gasser days, my neighbour told me about what cjm7171 mentions in the #1-4 at the beginning of this thread ... sans the smoke.
Tried it, and loved it! In fact, that's pretty much only what my gasser gets used for these days in regards to cooking.
The crispy skin is fantastic! Some sour cream, chopped green onions, shredded cheddar cheese .. S&P ..
I have also done the charcoal method on the kettle, as well as the foiled method in the basement.
In the end, you got cooked potatoes, and they are one of the finest food groups in my opinion.
